Im doing a physics project and am finding it very hard to explain why increasing pressure increases temprature as the energy of the particals surley would not change.
Can anyone help?

This is Boyle's law, but you can think of it this way...
When there is little pressure, the atoms just move around with each other and as such don't hit each other very hard. They get to keep their electrons as a result. As you increase the pressure the atoms are forced together and this results in more hitting and more electron release. The energy from that release causes the temperature to increase.
Volume changes work in the sam way that temperature changes do.

Because pressure puts the same amount of energy into a smaller volume. That translates to the temp going up, but the actual energy stays the same (except for what the pump adds).

Work is done during the increase in pressure. By the principle of conservation of energy, that work goes somewhere. One of those somewheres, is heat.

because if you increase pressure, molecules collide more with the walls of the container, thus bouncing around more and moving faster. faster movement = higher kinetic energy, and higher kinetic energy always means higher temperature.

The particles are more compressed as you increase pressure so they "bump" into each other more often.
You can also explain it by this equation:
PV=nRT

it's based on Boyle's law...do a search on boyle's law
