• Acts in every direction, not just pushing down.

Which of the following are true according to KMT when transferring a gas from a smaller container to a larger container?

• The gas particles will stay clumped together in a corner of the larger container.

• The gas particles will fill the new container and then stop moving.

• The gas particles will avoid colliding with one another, swerving out of the way if necessary.
