Learn about gas pressure and how it is used in daily life in this KS3 Chemistry guide from BBC Bitesize.

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.

These five terms are: the pressure (P), volume (V), number of moles (n), a constant (R)—with a value of 8.3145 joules per kelvin-mole—and temperature (T). You can't understand the ideal gas ...
