Liquid State
Intermolecular forces in liquids are collectively called van der Waals forces. These forces are essentially electrical in nature and result from the attraction of charges of opposite sign.
The principal kinds of intermolecular attractions are: dipole-dipole attractions, London forces, and hydrogen bonding.
Dipole-dipole attractions exist between molecules that are polar. This requires the presence of polar bonds and an unsymmetrical molecule. These molecules have a permanent separation of positive and negative charge. For example HCl, H atom is always slightly positive and the Cl atom is always slightly negative, the H atom in one molecule is attracted to the Cl in a neighbor.
London forces exist in nonpolar molecules. They result from temporary charge imbalances. Temporary charges exist because the electrons in a molecule or ion move randomly in the structure. The nucleus of one atom attracts electrons form the neighboring atom. At the same time, the electrons in one particle repel the electrons in the neighbor and create a short lived charge imbalance.
Hydrogen bonding is unique and requires two conditions: Covalent bonds between an H atom and either F, O, or N atom, and interaction of the H atom in this kind of polar bond with a lone pair of electrons on a nearby atom with F, O, or N. Hydrogen bonding can increase boiling point(ehh) and is responsible for the expansion of water when it freezes.
Structural differences between solids, liquids and gases:
Liquid crystals are an intermediate stage between solids and liquids. Some organic solids having long rod-like molecules which do not melt to give the liquid substance directly, they pass through the liquid crystal state first.
In a liquid, the molecules have a random arrangement and are able to move past each other. In a solid crystal, molecules have an ordered arrangement and are in fixed positions. In a liquid crystals, however, molecules are arranged parallel to each other and can flow like a liquid. Thus the liquid crystals have the fluidity of a liquid and the optical properties of a solid.
Liquid crystals are classified into three types: Nematic, Smectic, and Chloesteric.
Nematic liquid crystals have molecules parallel to each other, but they are free to slide or roll individually.
Smectic liquid crystals also have molecules parallel to each other, but they are arranged in compact layers. The layers can slide past each other.
Chloesteric: molecules are again parallel and arranged in layers, but molecules in successive layers are slightly rotated with respect to the layers above and below so as to form a spiral structure.

CC. Chlo. Chloester.
I love plenty things about you, trust, but I really love your big ole brain. I'm all but willing to let you keep the braincells between the two of us, thanks for letting me borrow them from time to time tho 😊
I love listening to you talk about stuff even if I don't understand completely what you're talkin about and I love that it doesn't take much for you to make me smile 💛
Mutuals send in a 💌and I'll tell you somethin that I love about ya :3

Im sorry im a ghost..even to myself . The Dark Ones took my soul piece by piece draining my blood and that of my family while they giggled hiding behind their many costumes. Chloe i am not alive since they tore us apart. Every time Id try and fight again they would hurt you and create more evil. I never have given up...everyday is a war...to stay alive as i cant live without being able to help you heal...protect you...the thought of you keeps me alive. Im always suffocating being for tortured for by taking a stand that id be honored to do again n again until the end of time just to show you how devoted I am...yet shattered into so many pieces. I obsessed with being free thinking of ways I could save you...I stare at pictures of you...sometimes Ill see the back of a girl with your haircolor and my heart stops while I stand in the street praying she’d turn around and be you. I would die simply to be blessed with one conversation with you. Sometimes I scream at God why? why? why? is my lionheart Chloester in places that just cant ever...ever...love and wanna do everything for you as much as I. I replay you getting back to me over and over in my mind. Ive dreamed of you every time I could sleep. So I started sleeping all day & night just so I could feel in some divine way our souls were visiting. I wake in panic many days thinking I gotta get Chloe to school...I look around and then im haunted again and again. I really dont believe Ill ever be happy again hoping for a miracle and somehow someway your running towards me my arms wide open. At 14ys old you now have the legal right to choose who you feel would benefit you in all the millions of ways you deserve. I feel so weak & battlescarred yet I need you to know how much I love you and wanted you so bad I couldnt go on. There is this world going on around me and I cant understand why Im paralyzed and everyone is just moving on...how could they couldnt they see mine had ended. I keep trying again and the loss of us is eating me alive...I hope you read this just to know my life stopped after I last saw you...they said you were getting to traumatized by seeing me and wouldnt allow no matter how many times I begged tried and pleaded. You are a galactic superstar...lionheart...sad yet so strong holding on for dear life. I am sick at the thought of how this is for you...I dont want you to be broken like me Chloe.
I LOVE YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
