Question

Raising the temperature of a gas will increase its pressure if which of the following happens?

a. the volume is increased, but the number of particles is constant.
b. volume is constant, but the number of particles is reduced.
c. both the volume and the number of particles are increased.
d. both the volume and the number of particles are constant.

Answer 1

Raising the temperature of a gas will increase its pressure if D. Both the volume and the number of particles are held constant.

Answer 2

d. both the volume and the number of particles are constant.

Explanation

Temperature increases the kinetic energy of the molecules. This increases the velocity of the molecules hence increasing the number of collisions with the walls of the container. This causes the pressure in the container to increase.

This will only happen if other factors are held constant. These factors are volume of the container and the number of particles/molecules.
