As magma rises, pressure
causing dissolved gases to expand and form bubbles. The size of the
bubbles increases, exerting a lot of force. The force of the expanding gases pushes the magma from the

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?
