What is a intensive property?
The value does not depend on the size of the system. ex pressure and density.
What is an extensive property?
A property that changes when the size of the system changes. Specific properties
What is thermal equilibrium?
If the temperature of the system is the same throughout the entire system.
What is chemical equilibrium?
If the chemical composition of a system doesn’t change with time.
What is an isothermal process?
Temperature is constant.
What is an isobaric process?
Pressure is constant.
Isochoric process?
V is constant
Cycle?
initial and final states are identical
What is a reversible process?
System and surroundings and be returned to their original states
Adiabatic process?
No heat lost to surroundings
What is a polytropic process?
PV^n = C (n is the polytropic index)
1J = 1N•M
true
What is the state postulate?
The number of properties required to fix the state.
