Measuring Vapor Apparatus
- For this purpose, water is heated in a closed pressure chamber at constant volume.
- Typical equilibrium states between gas and liquid phases can be set up.
- This allows for investigations to be performed on real gases andvapours.
- The high-pressure steam apparatus makes it possible to measure steam pressure in a temperature range of 100-250 °C.
- Heat of vaporisation is determined at various temperatures from the measurement of vapour pressure as a function of temperature.
