The pressure of a gas when cooled at constant volume will decrease because the molecules
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 constant volume, its molecules lose kinetic energy and move slower. This means that they collide with the walls of the container less frequently, resulting in a decrease in pressure. The other options given are incorrect:
- The number of molecules does not change, so is incorrect.
- The average kinetic energy remains the same, so is incorrect.
- The gas molecules do not break up into smaller molecules, so is incorrect.
