Question

Does pressure increase with temperature?

Answer 1

Hint: To solve this question one must have an understanding of the relationship between temperature and pressure and then one can easily solve this problem. In a close environment it is seen that, in a direct relationship, one variable follows the same change when it comes to increasing and decreasing.

Complete answer:
There are 2 ways pressure increases:
1. A temperature shift occurs. The average kinetic energy and speed of the particles will grow as the temperature rises. As a result, these particles strike the container's walls more frequently and violently. Increased pressure results from this.
2. The volume shifts. Since there are more particles per unit volume as volume declines, the particles impact the container walls more frequently and violently, increasing the force per unit area, or pressure.

In general, we can state that a gas's kinetic energy is temperature-dependent. Gas molecules have an increase in kinetic energy as temperature rises. The walls of the container will collide with the faster-moving molecules more frequently and violently. This will increase the pressure by increasing the force acting on the container's walls.
We can conclude that,
${\rm{P}} \propto {\rm{T}}$

This means, that as the pressure increases temperature also rises similarly with a fall in pressure there will be a fall in temperature and vice versa.

Hence yes, the pressure increases with the temperature.

Note: The temperature rises with the increase in average kinetic energy of the particle increases. The average kinetic energy of particles will remain constant regardless of volume change. Therefore, a change in volume that causes a change in pressure won't change the temperature.
