Concept explainers
(a)
Interpretation:
The effect on the pressure of the gas should be identified if the initial volume is halved and double the temperature.
Concept introduction:
Different laws have been put forward to introduce properties of gases:
Boyle’s law:
At fixed temperature, the volume of a fixed amount of gas is inversely proportional to the pressure exerted by the gas.
Charles law: States that volume is directly proportional to temperature when the gas is held
at constant pressure and number of molecules.
General

General Gas Law: Combining Charles’s law and Boyle’s law we get the General gas law or Combined gas law.
