Introduction

What is thermodynamics?

Thermodynamics is about how matter responds to changes in its environment or system! This could mean temperature, pressure, volume, or even composition. They could all change, or only one could change. We also use terms derived from these bases.

All in all, it’s the study of the relationships between the equilibrium of a system and whatever changes happen to it. This is super duper important to remember!

What is a state?

A state has a particular mass, velocity, position, mode(s) of motion, etc... Basically, it’s like looking at a picture of a boat with a little description of everything going on in that picture. Where does the boat exist? How hot is it? How big is it? Are there other boats? Is it moving? Specifically, this is a macroscopic state description. If you knew about all of the particles within that boat, that would be a microscopic state.

What do you mean by fixed state?

How can a state be broken? The heck?

What we mean by fixed is that there are no changes to the state. Remember those base terms I mentioned earlier? Fixing a few of those will fix everything else in the state because of how they are related to each other (this can get complicated depending on the system). Below is an example of the notation for pressure at a fixed volume:

PV = !Equation bits!

What’s that ideal gas law again?

I’m so glad you asked! It’s an equation used for gases in which we assume that:

A. There are a lot of particles spread far apart

B. The collisions between the gas and the walls of the container are elastic (no loss of kinetic energy)

C. The particles are in continuous, rapid, and random motion

D. There are no forces of attraction between particles

E. The temperature of the gas depends only on the kinetic energy of any moving object

These are a lot of assumptions, but personally I think assumptions B and D are the most important to remember (these are arbitrarily assigned, there’s no standard order of lettering/numbering). Below is the equation:

PV’ = nRT

This describes the state of the system. That is, V’ is the volume of the entire system! Without the apostrophe, it is the molar volume (Volume per mole). P is pressure, n is moles, R is the gas constant, and T is temperature in Kelvins. We have two different values for R depending on the units of your terms.

(Ideal Gas Law with V’)

PV = RT

R = 0.082057 L*atm / mol*K

R = 8.3144 J / mol*K

That’s it for now! We’ll continue with more important definitions in future posts!

*Please give me any feedback or questions you may have! I love questions, and it helps me learn and understand better

Fixed State

At twenty-five, Max has spent the majority of her adult life fleeting from one place to another. She knows she's chasing after dreams and when she bumps into Warren, she lets herself get wrapped in his awkward charm just for the sake of the distraction. And now, two months into this chaos, she still has no idea of what she’s doing. She likes the way his eyes follow her as soon as she enters a room, how she doesn’t have to try much to make him happy. She does not like how he pushes and pushes against her, even when there's no bed beneath them, as if by being close enough, he can get her to spill all her thoughts. They are in a fixed state, unyielding. Something has to give. Read it here on AO3.
