Thermodynamics Flashcards
1
Q
0th law of thermodynamics
A
law about thermal equilibrium
If object a is in thermal equilibrium with object b and object b is in equilibrium with object c THEN object a and object c are in thermal equilibrium too
2
Q
What phase change results in the greatest increase of entropy?
A
Sublimation (solid to gas)
3
Q
True or false: entropy increases from gas to liquid to solid
A
False: entropy decreases with increasing order of molecules (solid= most ordered)
4
Q
What is an isolated system?
A
A system that cannot exchange energy (heat and work) or matter with its surroundings (ΔU=0)
