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 are calculated from the pressure or volume change.
- Determination of cp and cv
- For both demonstration and student experiments
- Suitable for many different gases
- Simplified implementation: all pre-settings already prepared
Determine the molar heat capacities of air at constant volume and at constant pressure.
