Temperature and pressure are always directly proportional.

Explanation:

There is no case where temperature and pressure are not directly proportional, when other variables remain constant. This is true for all states of matter.
On a particle level, the higher the temperature the more energetic the particles so the number of collisions increase.

Any case where it appears that pressure and temperature are indirectly proportional, are cases where volume is not constant.
