What happens to the particles in a gas when the temperature increases? how does this affect the pressure of the gas?

Hotter it gets the more the pressure, the particles start bouncing faster when it gets hotter, therefor making the pressure higher

The particles in gas, when heated will expand. Making the pressure more compact. Also making the gas very flammable.
