Question

question 4
what is the relationship between wall collisions and pressure?
there is no relationship. wall collisions do not affect pressure.
there is an inverse relationship. when wall collisions increase, pressure decreases.
there is a direct relationship. when wall collisions increase, pressure increases.

Explanation:

To determine the relationship, we recall the kinetic theory of gases. Pressure in a gas is caused by gas particles colliding with the container walls. More wall collisions (from faster or more frequent particle movements) mean more force per unit area, so pressure increases. So when wall collisions increase, pressure increases (direct relationship). The first option is wrong as collisions do affect pressure. The second is wrong because inverse would mean one increases as the other decreases, but here they increase together.

Answer:

C. There is a direct relationship. When wall collisions increase, pressure increases. (assuming the third option is labeled C; if the original options had labels like A, B, C, adjust the label as per the original, but based on content, the correct one is the third option stating the direct relationship)
