Question

Which of the following most likely happens when the number of particles of a gas decreases? (5 points) Group of answer choices The pressure of the gas increases. The pressure of the gas remains same. The number of collisions of gas particles decreases. The number of collisions of gas particles remains same.

Answer 1

The number of collisions of gas particles decreases.

Step-by-step explanation:

This is because the number of collisions between gas particles and the walls of the container is directly proportional to the number of particles. When there are fewer particles, there are fewer collisions with the container walls, resulting in less force applied per unit area, and therefore, a decrease in pressure.
