Fig. 1.13: Air in a closed container | As with all gases, the air consists of molecules. The molecules are held together by molecular force. If the air is enclosed in a tank (constant volume), then these molecules bounce off the walls of the tank and generate pressure p.
The higher the temperature, the greater the movement of air molecules, and the higher the pressure generated.
Volume ( V ) = constant
Temperature ( T ) = is increased
Pressure (p ) = r i s e s
Boyle and Mariotte carried out experiments with enclosed volumes of gas independently of each other and found the following interrelationship:
The volume of gas is inversely proportional to pressure.
( Boyle-Mariotte’s Law )
