Are these statements true or false?

1. Gas particles slow down when they collide with the walls of a container.
2. The speed of gas particles are not affected by collisions with other gas particles.

I think they are both false since the collision of one particle with another (or the walls of its container) is completely elastic. Am I correct?

You are correct. Both statements are false.

1. Gas particles do not slow down when they collide with the walls of a container. In an ideal gas, the collisions between gas particles and the walls of the container are perfectly elastic. This means that the particles rebound from the walls without losing any kinetic energy. As a result, the speed of the gas particles remains constant.

2. The speed of gas particles can be affected by collisions with other gas particles. During a collision between gas particles, the momentum of the particles may change, resulting in a transfer of energy and a change in the speeds of the colliding particles. These collisions can lead to changes in the overall speed and direction of gas particles.

To determine the accuracy of statements like these, it is helpful to understand the behavior of gas particles using the kinetic theory of gases, which describes the motion of gas particles based on their collisions and interactions.
