You Be the Teacher - Thermodynamics
Term | Definition |
---|---|
Potential | energy due to relative position |
kinetic | energy due to relative velocity |
internal energy | kinetic + potential energy with all the basic building blocks (atoms, molecules, etc.) of a system |
work | energy changing systems due to pressure change |
Heat | energy changing systems due to temperature change |
Closed system | same amount of stuff (mass), but energy can be transferred but cannot go through system boundaries |
Temperature | a measure of the relative hotness or coldness of a material |
pressure | the normal (perpendicular) component of force per unit area |
Volume | the quantity of space possessed by a material |
Entropy | the quantity of disorder possessed by a material |
thermodynamic cycle | a process for which the final and initial states are the same |
heat capacity | the amount of energy required to increase the temperature of one unit quantity of material by one degree |
Enthalpy | internal energy plus the pressure-volume product |
Closed system | same amount of stuff in it; energy can be transferred but mass cannot (past “system boundaries”) |
Open system | in a specific place; mass and energy can be transferred (“system boundaries”) |
Isolated system | energy and mass cannot be transferred (“system boundaries”) |
Internal energy | 𝚫U = Q - W |
U | internal energy |
Q | Heat |
W | Work |
(Delta) | Change |
