This very accurate apparatus is used to study the compression and the liquefaction of gas, to determine the critic point, and to detect isothermal lines on […]
The boiling point of a solution is always higher than that of pure solvent. A special apparatus enables to determine how the difference of temperature (boiling-point […]

The device helps students to determine the molar mass of a pure liquid by evaporating the same liquid at a constant temperature and pressure and measuring […]
The freezing point of a solution is always lower than that of pure solvent. A specific instrument (cryoscope) will determine freezing-point depression in experimental way. If […]
Water is heated inside a closed chamber under pressure; water will vaporize when the pressure inside the chamber corresponds to the steam pressure at that temperature. […]
This equipment enables to study steam tension in the temperature range of 40-85°C. Clausius – Clapeyron equation describes the relationship existing between temperature and pressure.
