Average energy in kinetic stores is related to temperature

The particles in a gas are constantly moving with random directions and speeds. If you increase the temperature of a gas, you transfer energy into the kinetic energy stores of its particles
The temperature of a gas is related to the average energy in the kinetic energy stores of the particles in the gas. The higher the temperature, the higher the average energy
So as you increase the temperature of a gas, the average speed of its particles increases. This is because the energy in the particles’ kinetic energy stores is 1/2mv2

Colliding gas particles create pressure

As gas particles move about at high speeds, they bang into each other and whatever else happens to get in the way. When they collide with something, they exert a force on it. In a sealed container, the outward gas pressure is the total force exerted by all of the particles in the gas on a unit area of the container walls
Faster particles and more frequent collisions both lead to an increase in net force, and so gas pressure. Increasing temperature will increase the speed, and also the pressure
Alternatively, if temperature is constant, increasing the volume of a gas means the particles get more spread out and hit the walls of the container less often. The gas pressure decreases
Pressure and volume are inversely proportional-when volume goes up, pressure goes down. For a gas of fixed mass at a constant temperature, the relationship is:
pV=constant, p=pressure, v=volume

The pressure of a gas causes a net outwards force at right angles to the surface of its container
There is also a force on the outside of the container due to the pressure of the gas around it
Ifa container can easily change its size, then any change in these pressures will cause the container to compress or expand, due to the overall force

If you transfer energy by applying a force, then you do work. Doing work on a gas increases its internal energy, which can increase its temperature
You can do work on a gas mechanically. The gas applies pressure to the plunger of the pump, and so exerts a force on it. Work has to be done against this force to push down the plunger
This transfers energy to the kinetic energy stores of the gas particles, increasing the temperature. If the pump is connected to a tyre, you should feel it getting warmer
