Charles's (Amontons') law

Principle

Amontons' law describes the relationship between the pressure and the temperature of a fixed quantity of gas at constant volume. A glass syringe enclosed in a glass jacket is used to capture about 50 ml of gas. The water in the glass jacket is warmed up graduall ...

Determination of the molar masses of metals

Principle

A piece of metal is weighed and placed in the insert of the reaction cylinder, whereafter an acid is added to the cylinder through the three-way valve until it is about half full. The metal is made to react with the acid by lowering the insert. The gas syringe c ...

Gas laws

Principle

The experiments for deriving the three gas laws with the glass jacket system can also be performed very conveniently on the comprehensive chemistry/biotechnology experiments panel.
To display the temperature and pressure measured during the demonstration, t ...

Charles' law

Principle

The ideal gas equation describes the thermal state of an enclosed gas with regard to the parameters of state; pressure p, volume V, temperature T and number of gas molecules n. It enables three different gas laws to be derived, each for the behaviour ...

Charles's (Amontons') law

Amontons law

Principle

The ideal gas law describes the thermal state of the gas enclosed in a vessel relative to the properties pressure p, volume V, temperature T, and amount of substance n.  It can be used to derive three different laws which describe how a gas behav ...

Boyle-Mariotte law

Principle

The general gas equation describes the relationship between pressure, volume and temperature of an enclosed gas volume. A gas syringe is used for measuring the relationship between the volume and the pressure, which is sealed with the help of motor oil. In addition ...
