Question 1 Report
The pressure of a gas when cooled at constant volume will decrease because the molecules
Answer Details
When a gas is cooled at a constant volume, its molecules lose kinetic energy and move slower, which means they collide less frequently with the walls of the container. This decrease in collisions results in a decrease in pressure. Therefore, the correct answer is: "collide less frequently with the walls of the container." The other options are not applicable to this scenario. The average kinetic energy of the molecules remains the same because there is no change in the temperature, and the gas molecules do not break up into smaller molecules or decrease in number because the cooling process does not involve any chemical reaction or physical changes in the gas.
