increasing the temperature doesnt change pressure.
increasing the temperature increases the pressure.
increasing temperature decreases the pressure.

Explanation:

First Question (Effect of Temperature on Particle Speed)

In the kinetic theory of matter, temperature is related to the average kinetic energy of particles. Higher temperature means more kinetic energy, which translates to higher average speed (since kinetic energy \( KE = \frac{1}{2}mv^2 \), so more \( KE \) implies higher \( v \) for particles with mass \( m \)). So increasing temperature increases particle speed.

For a fixed volume (or in gas laws context, like Gay - Lussac's law for constant volume), as temperature increases, particle speed (and kinetic energy) increases. Faster - moving particles collide with the container walls more frequently and with more force, leading to higher pressure. So increasing temperature increases pressure (assuming volume and amount of gas are constant).

Answer:

A. Increasing the temperature increases the speed of the particles.
