Pressure and Temperature - Advanced Terminology
Molar Heat Capacity (J mol-1 K-1)
Molar heat capacity is the energy required to heat a mole of a substance by 1 K.
Young's modulus (GPa)
Young's modulus is a measure of the stiffness of a
substance, that is, it provides a measure of how difficult it is to extend a
material, with a value given by the ratio of tensile strength to tensile
Shear modulus (GPa)
The shear modulus of a material is a measure of how
difficult it is to deform a material, and is given by the ratio of the shear
stress to the shear strain.
Bulk modulus (GPa)
The bulk modulus is a measure of how difficult to compress a substance. Given by the ratio of the pressure on a body to the fractional decrease in volume.
Vapour Pressure (Pa)
Vapour pressure is the measure of the propensity of a substance to evaporate. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system.
