molar thermal capacity

Molar thermal capacity, also known as molar heat capacity, is the amount of heat required to raise the temperature of one mole of a substance by one Kelvin. It is a measure of how much heat a material can absorb for a given temperature change, expressed in units like calories per mole per Kelvin or joules per mole per Kelvin.12

This property is crucial in thermodynamics for understanding how substances respond to heat. For example, water has a high molar heat capacity, meaning it takes a significant amount of heat to increase its temperature. The molar heat capacity can differ depending on whether the pressure or volume is held constant during heating, with constant pressure typically requiring more heat due to the work done by expansion.1
