We know that for an ideal gas the differential of the internal energy function is:
dU = n Cv dT
But is Cv the molar heat capacity or not?
dU = n Cv dT
But is Cv the molar heat capacity or not?
The molar heat capacity of an ideal gas is the amount of heat energy required to raise the temperature of one mole of the gas by one degree Celsius at constant pressure.
Molar heat capacity is the amount of heat energy required to raise the temperature of one mole of a substance, whereas specific heat capacity is the amount of heat energy required to raise the temperature of one gram of a substance.
The molar heat capacity of an ideal gas is directly proportional to temperature. This means that as the temperature increases, so does the molar heat capacity.
The molar heat capacity of an ideal gas is dependent on the molecular structure and composition of the gas. Different gases will have different molar heat capacities, but they will all follow the same relationship with temperature.
The molar heat capacity of an ideal gas can be measured experimentally by using a calorimeter. The gas is placed in a container and its temperature is measured before and after adding a known amount of heat energy. The change in temperature and amount of heat energy can then be used to calculate the molar heat capacity.
