[tenth-sentence]

An endothermic reaction can not become exothermic by using a catalyst.

A potential energy diagram for an endothermic reaction, where the potential energy of the products is higher than that of the reactants (∆H > 0), is shown in figure 15.16.

There is a happiness no-one else knows: the feeling of mud between fully webbed toes; the caress of a breeze on your moist shiny skin; the warmth of the sunlight that slowly soaks in; the gentlest hum of a thought far away, as you sit and you soak and let time tick away.

actually doesnt blaze use a blanket in book 3 because she's cold. The dragons are warm-blooded ?

There is this whole idea that flipping a two sided coin doesn't have a 50-50 probability. It's not a new idea by any means, but the explanation is if you measured the mass of the coin, the force of the flip, the temperature of the coin & of the room, the force of any breeze, wind, or vibration in the air as it traveled, and so on, you could accurately determine within a small margin of error what side the coin will land on every time, and if you kept those constant it would flip on the same side every time. And that idea is also KIND OF the explanation for the conclusion in quantum physics that there is no free will.

A lot of people hear that and either clutch their pearls, roll their eyes, or aren't interested either way. (I mean, when you say some shit like that you're just going to immediately turn off any interest most people would have otherwise had but I'm digressing now). We all like to think we make decisions and choices, and then amateurs who want to talk about quantum mechanics alienate everyone by saying it's not true: you were always going to make these choices with no chance to make the other one.

But what I said in the first paragraph is something-like (but not exactly) what it means when you hear or read that according to quantum physics we have no free will. That if we had an unfathomable device that has been measuring all the variables of every single particle that was expelled during the Big Bang, with an also-sufficient/also-currently-unfathomable algorithm to plug those variables into, all within a computer that could do all of the calulations for BILLIONS of years, we could compute exactly where every particle was going and where it would end up, including those that make up the stars and planets, that make up the ground and oceans, that make up the animals and plants, that make up your brain and all of the proteins and neurotransmitters. That if it could all be measured and an algorithm sufficiently built then the decisions you make are already determined by the ongoing relationships and interactions the particles that make up your brain had in the past and are having right now.

However, humans cannot measure that, they likely never ever will.

Anyone that tells me they don't like quantum mechanics because something something affront to nature blah blah "they" don't believe in free will, etc. literally doesn't know it's just a rescale of the coin toss description. You still believe coin tosses are 50-50 because you aren't going to measure the variables used to receive an answer, you can still believe in free will because you can't measure the variables used to determine the ultimate path of all particles; I mean, I wouldn't become a theoretical physicist if that meant so much to you but I'm not your dad, do what you want.

Edit: I know I described the science mostly wrong, please check out the replies and reblogs for others' corrections and feel free to add corrections of your own for mine and others' learning, thank you.

Endotherm (Thomas Wilkins) was introduced in The Invincible Iron Man #136, cover date July, 1980. He was created by Peter John Palmer, David Michelinie, and Alan Weiss. ("The Beginning of Endotherm", The Invincible Iron Man #136, Marvel Comic Event)

As you can see from figure 10.12, the first step is endothermic.

[whats-in-a-sentence]

The enthalpy change when a gas dissolves in a liquid has essentially two contributions, as shown in figure 10.3 on the next page.

Energy is required to open 'pockets' in the solvent that can hold gas molecules. The solvent must be expanded slightly to accommodate the molecules of the gas. This is an endothermic process since attractions between solvent molecules must be overcome. Water is a special case – it already contains open holes in its network of loose hydrogen bonds around room temperature. For water, very little energy is required to create pockets that can hold gas molecules.

Energy is released when gas molecules enter these pockets. Intermolecular attractions between the dissolved gas molecules and the surrounding solvent molecules lower the total energy, and energy is released as heat. The stronger the attractions are, the more heat is released. Water can form hydrogen bonds with some gases, such as NH3, whereas many organic solvents cannot. More heat is released when such a gas molecules is placed in a pocket in water than in organic solvents.

I'm feeling very (post) biology major seeing everyone's walrus vs fairy takes. Just saw a post from a popular blogger say the discovery of fairies wouldn't be that big or interesting to biology, wtf are you talking about? Anyways, I'm dissecting the fairy
