Solution

## Thermodynamics: The study of the relations between heat, work, temperature, and energy.Properties of thermodynamics:PropertyDefinitionSymbolUnitsChemical PotentialChemical potential is the energy that can be absorbed or released due to the change in the number of particles α$\mathrm{kJ}/\mathrm{mol}$DensityThe density of a substance is its mass per unit volume.ρ $\mathrm{kg}/{\mathrm{m}}^{3}$EnthalpyEnthalpy is a property that is equal to the system’s internal energy plus the product of its pressure and pressure and volumeH$\mathrm{J}$EntropyEntropy is closely related to the microscopic configurations that are consistent with the macroscopic configurations that characterize the system.S$\mathrm{J}/\mathrm{Kg}$Heat CapacityHeat capacity is defined as the amount of heat to be supplied to a given mass of a material to produce a unit temperature. Cp$\mathrm{J}/\mathrm{K}$Specific Heat CapacityIt 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$\mathrm{J}/\mathrm{K}$Internal PressureIt is the measure of how the internal energy of the system changes when it expands or contracts at a constant temperature.πT$\mathrm{Pa}$Thermal ConductivityIt is the measure of the ability of a system to conduct heat.k$\mathrm{W}/\left(\mathrm{m}.\mathrm{k}\right)$Specific VolumeIt is the ratio of the substance’s volume to its mass.v${\mathrm{m}}^{3}/\mathrm{kg}$
