What is true of all particles of gas enclosed within a container?

They move at different speeds.

They have the same kinetic energy.

They never collide with each other.

The first statement, "They move at different speeds," is true of all particles of gas enclosed within a container. The second statement, "They have the same kinetic energy," is not necessarily true as the kinetic energy of gas particles can vary depending on their mass and velocity. The third statement, "They never collide with each other," is false as gas particles frequently collide with each other within a container.
