Alidded glass container is filled with a colored gas. after a period of time, it is observed that the gas is uniformly spread throughout the box and that the movement has slowed considerably. next, a warm iron plate is carefully placed under the box. why is there resumed movement of the gas in the container? a) the warm iron plate absorbed energy from the gas particles, making them move faster. b) the warm iron plate vibrated due to the energy it had, disturbing the gas in the process. c) heat from the warm iron plate transferred energy to the gas particles, making them move faster. d) the warm iron plate heated the insulated box causing it to vibrate, disturbing the gas in the process.
