Physical Chemistry Test 2

Exact differential

Does not depend on path

Inexact differential

Depends on path

Heat Capacity

Cv= (dU/dT)v

Internal pressure

Pit=(dU/dV)T

Spontaneous change

Change that happens without doing work

Non spontaneous change

Change when work is done

Entropy

The measure of dispersal/disorder of energy/matter

Reversibility

Smooth and restrained transfer of heat between two bodies at the same temperature

Statistical entropy

Distribution of the molecules over available states

Microstates

Energies or physical state of matter at particle level

Configuration

The number of ways that molecules can be arranged in a system, while still maintaining the same total energy

Second law of thermodynamics

Entropy of an isolated system increases during a spontaneous change

First law

The energy the universe is constant and energy is conserved

Second law

The universe is a disordered space due to spontaneous processes

Third law

The entropy is dependent on temperature

Isobaric

Constant pressure

Isochloric

Constant volume

Isothermal

Constant temperature
