State Property

Postby Sabah Islam 1G » Sun Jan 14, 2018 9:37 pm

Can someone explain what exactly a state property is? How do you know the difference of something being a state property versus something not being a state property?

A state property is a value that is calculated purely by the final value - initial value. I think the only non-state properties we need to be concerned about at this point are work and heat, which Lavelle mentioned in class.

According to my understanding, state property, like temperature, describes the state of something. A cup of water is currently at 25℃ no matter now the water get to that temperature. Heating that cup of water from 0℃ to 25℃ or from 10℃ to 25℃ require different amount of heat. So heat is not a state property since for heat the path does matter.

State properties include enthalpy, volume, temperature, pressure, density, heat capacity, and energy.
