Chemical Potential

Chemical potential is the energy that can be absorbed or released due to the change in the number of particles 

α

kJ/mol

Density

The density of a substance is its mass per unit volume.

ρ 

kg/m3

Enthalpy

Enthalpy is a property that is equal to the system’s internal energy plus the product of its pressure and pressure and volume

H

J

Entropy

Entropy is closely related to the microscopic configurations that are consistent with the macroscopic configurations that characterize the system.

S

J/Kg

Heat Capacity

Heat capacity is defined as the amount of heat to be supplied to a given mass of a material to produce a unit charge. 

Cp

J/K

Specific Heat Capacity

It is the amount of heat that must be added in the form of heat to one unit of mass of the substance in order to cause an increase of one unit in its temperature. 

Cv

J/K

Internal Pressure

It is the measure of how the internal energy of the system changes when it expands or contracts at constant tempertaure.

πT

Pa

Thermal Conductivity

It is the measure of the ability of a system to conduct heat.

k

W/(m.k)

Specific Volume

It is the ratio of the substance’s volume to its mass.

v

m3/kg
