reading actual medical case reports bc of house and realizing that perhaps cheating through every single science class i ever took is having unforseen consequences (cant understand yaoi subtext as deeply as i could)
#like WHAT THE FUCK IS THE LYMPHATIC SYSTEM#ur telling me plasma and lymph is the same that there's just free floating juice in me??? i thought plasma were just a type of blood cell??#sooo lost rn unbelievably cooked. thank god i didnt become a nurse#i have like five pages of notes rn this is crazy. very interesting too but still goddamn.#quizlet got me through years 7 - uni of mandatory science classes this is so bizarre

can my history teacher please shut the fuck up i get it’s a college class!! i get that! you don’t need to keep telling me i’m gonna fail!!
#the same thing happened when i took ap world except that teacher ended up actually being really good#this guy just won’t shut up about how i’m gonna be ‘put on academic probation no matter what college i attend’#like okay? your class is only relevant if i’m gonna stay in new york#idk i think that’s how these credits work#i’m so gonna end up nkt okay this year jus preparing y’all now#we got two college history college spanish college physics and the rest of my core claaaes are all honors#and i’m taking two art classes and choir every other day because that’s the only way that fit in my schedule#with no lunch or study hall save for every other day for the latter#and if i do get to eat it’s gonna be at 7 in the morning every other day#yippee!!#i did this to myself i have no right to be bitching#idk i’m not gonna take the deep dive into why i did this to myself#least ill have enough creds to graduate lmfao#also science counts as an elective for me since in ny you only need 3 science creds to graduate and i have all 3#idk why i’m doing this#the outsiders will be my reward#for getting through a month and a half of this shit#i have no right to be complaining that isn’t that hard of a schedule#anyway!#alaska’s bitching#it just bugs me when he says i’m gonna be out on academic probation like yes colleges will see i got a b in college history in my junior#<year and crucify me on campus#totally logical#regents

well. "make wordsearch puzzles of minecraft youtube characters"
#osh has thoughts#“during math class instead of studying for a test that i'm genuinely worried about” “directly after a science test” “instead of learning#“lines for something due tomorrow” “while rewatching a tv show i don't care about” “instead of writing 2/7 of a story“ ”instead of figuring#“out why minecraft doesn't work anymore” etc etc

sometimes I just lay in bed and think back to just how practically everyone in my secondary school got fucked over mentally hy it being a grammar school
I got good grades most of us did in the GCSE and a level, but at what cost. The cost of our sanctity of mind.
#A 7. What is equivalent to a A- to B+ Was frowned upon#Every exam there was at least 6 kids who had a mental breakdown but still continued the exam#Like in class too#Wr were constantly made to do work a year ahead of what we should have been doing. And the teachers seemed proud of that#Idk i might have also been at a disadvantage because my primary school was shit and we never did anything useful for secondary#I just got punted into.it and asked to cope#I had never done science history or geography before year 7. And we were immediately punted into a year.8 standard#Almost everyone I know was broken by the grammar school system. Anxiety and a crippling fear if failure

why is my lit professor insane and not in a good way
#things she's told us in the span of 4 weeks:#1. blatantly wrong historical information#2. blatantly wrong geological information#3. blatantly wrong paleontological information#4. ancient aliens gave us math and science way back when India was first settled#5. the catholic church is at fault for every single thing wrong in this world#6. hitler didn't kill himself he fled to argentina and died there#7. everyone in europe sucks except the french cuz they're cool about sex ???#cannot wait to expand on this list#genuinely annoying this insanity only became evident AFTER the deadline to drop classes without penalty. smile :)

COMPLETELY FORGOT i did technically take cooking classes as a. like. extracurricular or something (?). so if you were a good student and got mostly As you could attend a regional school on saturdays and you got your pick of whatever classes you wanted per semester (fall and spring). like woodshop/science/cooking/art/writing/etc and this was mostly for late elementary/middle school. but i think woodshop was available through highschool. i did take cooking there. and also woodshop/engineering. and science. and art.
#i took two semesters of science? one of woodshop. one of art. and like three of cooking. lol.#but yeah at the time i was doing this i was at school 7 days a week#normal school week. then the saturday classes. and then ccd on sundays.

What is the difference between heat and temperature class 7
Understanding the Difference Between Heat and Temperature
For Class 7 students, understanding the concepts of heat and temperature is essential as these are fundamental topics in physics that explain how energy is transferred and how we measure it. Despite their close relationship, heat and temperature are distinct concepts. This article will delve into their definitions, differences, and how they relate to each other in the context of everyday life and scientific principles.
What is Heat?
Heat is a form of energy known as thermal energy. It is the energy that is transferred between systems or objects with different temperatures. Heat flows from the hotter object to the cooler one until thermal equilibrium is reached, meaning both objects attain the same temperature.
Key Points About Heat:
Energy Transfer: Heat is the transfer of thermal energy from a warmer object to a cooler one.
Units: Heat is measured in joules (J), calories (cal), or British Thermal Units (BTU). The joule is the standard unit in the International System of Units (SI).
Forms of Transfer: Heat can be transferred in three ways – conduction (direct contact), convection (fluid movement), and radiation (electromagnetic waves).
What is Temperature?
Temperature is a measure of the average kinetic energy of the particles in a substance. It indicates how hot or cold an object is but does not measure heat directly. Temperature tells us the intensity of heat present in the substance.
Key Points About Temperature:
Measure of Kinetic Energy: Temperature measures the average kinetic energy of particles in a material.
Units: Temperature is measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K). The Kelvin scale is the standard in scientific contexts.
Thermometers: Temperature is measured using thermometers, which can be liquid-in-glass (like mercury or alcohol thermometers), digital, or infrared.
Differences Between Heat and Temperature
Understanding the differences between heat and temperature is crucial for grasping basic principles of thermodynamics and everyday phenomena.
Nature:
Heat: Heat is a form of energy.
Temperature: Temperature is a measure of the intensity of heat.
Measurement:
Heat: Measured in joules (J), calories (cal), or BTU.
Temperature: Measured in degrees Celsius (°C), Fahrenheit (°F), or Kelvin (K).
Concept:
Heat: Refers to the total energy of molecular motion in a substance.
Temperature: Refers to the average energy of molecular motion in a substance.
Instrument:
Heat: Measured using calorimeters.
Temperature: Measured using thermometers.
Transfer:
Heat: Can flow from one body to another.
Temperature: Is an indicator and does not flow.
Practical Examples and Applications
To better understand the concepts of heat and temperature, let's consider some everyday examples:
Boiling Water:
When you heat water on a stove, the stove provides heat (thermal energy) to the water. As the water absorbs this heat, its temperature rises. Once it reaches 100°C (at standard atmospheric pressure), it begins to boil. Here, the heat energy causes the water molecules to move faster, increasing their kinetic energy and, consequently, the temperature.
Heat Transfer in a Metal Rod:
If you hold one end of a metal rod in a flame, heat travels along the rod through conduction. The end in the flame gets hot first (higher temperature) as heat is transferred to it, and this energy moves along the rod, increasing the temperature of the entire rod over time.
Room Heating:
In winter, a heater transfers heat to the air in a room. The heater's temperature is higher than the room's air temperature, and heat flows from the heater to the air, increasing the room's temperature until equilibrium is achieved.
Thermodynamic Principles
The relationship between heat and temperature is governed by the principles of thermodynamics, particularly the first law (conservation of energy) and the second law (entropy). These laws describe how heat energy is conserved and how it naturally flows from hotter to cooler bodies, respectively.
First Law of Thermodynamics:
This law states that energy cannot be created or destroyed, only transferred or converted from one form to another. When you heat a substance, the energy you provide (heat) is converted into internal energy, raising the substance's temperature.
Second Law of Thermodynamics:
This law explains that heat flows spontaneously from a hot object to a cold one and not in the reverse direction unless external work is applied. This principle underlies many natural processes, such as the melting of ice in a warm room.
Experimental Activities
For a practical understanding of heat and temperature, students can perform simple experiments:
Mixing Water:
Mix hot and cold water and measure the final temperature. This experiment demonstrates heat transfer and equilibrium. The final temperature will be intermediate, depending on the masses and initial temperatures of the water samples mixed.
Heat Absorption:
Place different materials (metal, wood, plastic) in sunlight and measure their temperature at regular intervals. This activity shows how different materials absorb and retain heat differently, affecting their temperature rise.
Conduction Experiment:
Heat one end of a metal rod and feel the temperature change along its length. Use a thermometer to measure how quickly the heat spreads. This experiment illustrates heat conduction.
Conclusion
In summary, heat and temperature are fundamental concepts in science that describe how energy is transferred and measured. Heat is the thermal energy transferred between objects, while temperature measures the average kinetic energy of particles in a substance. Understanding these concepts is essential for studying thermodynamics and applying this knowledge to real-world situations. By exploring the differences between heat and temperature, students can appreciate the intricate ways energy interacts with matter in our everyday lives.
