The relationship between pressure, temperature, and volume of an ideal gas.

 The relation between temperature, volume, and pressure is simple when you put it like this:

• Temperature + volume = directly proportional 
• Temperature + pressure = directly proportional 
• Volume + pressure = inversely proportional 

This means that if volume or pressure increase the temperature will increase, but if the volume increases the pressure will decrease and vice versa. 

This graph shows it in further more detail:

In the first graph, it shows that if the pressure increases the volume decreases. And in the second, It shows that as long as the volume increases temperature also increases. In the third, it also shows that if the pressure increases the temperature would also increase. And in the last it shows that when volume increases the pressure then decreases.
