Gas Properties
Volume, V: This is the space occupied by the particles that make up the gas.
Volume is measured in metres cubed, m3
Temperature, T: This is a measure of the internal energy of the gas and this is equal to the average kinetic energy of its particles.
Temperature is measured in Kelvin, K
Pressure, p: When a gas particle collides with the walls of its container it causes a pressure. Pressure is given by the equation pressure = Force/Area or ‘force per unit area’.
Pressure is measured in pascals, Pa
1 pascal is equal to a pressure of 1 newton per square metre.
