What happens to the molecules when a gas is compressed? a. they maintain their temperature. b. there is a drop in temperature. c. there is a rise in temperature. an unopened bag of chips expanding as one drives up a mountain is a good example of how volume a. decreases when pressure decreases b. decreases when pressure increases c. increases when pressure decreases d. increases when pressure increases

B. There is a drop in temperature

C. increases when pressure decreases

Explanation:

With constant pressure, the volume is proportional to the temperature. Since the temperature is directly related to the average kinetic energy of the gas molecules. So, the lower the volume (compression), the lower the speed of the molecules (temperature).

On the other hand. With constant temperature, when the pressure increases, the volume drops, while if the pressure decreases the volume increases.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
