Heat is added to a gas in a glass vessel by an electric heater which is switched on briefly. The temperature increase results in a pressure increase, which is measured with a manometer. Under isobaric conditions, a temperature increase results in a volume dilatation which can be read from a gas syringe. The molar heat capacities Cv and Cp are calculated from the pressure or volume change.
