The diagram on the far left shows the moving particles of a gaseous material within a rigid container. Which of the three boxes on the right best represents this material upon the addition of heat?

Question

Quizplus · Accepted Answer

Box B best represents the addition of heat to the gaseous material because it shows the particles moving faster, which is what would happen as the temperature of the gas increases. Box A shows the particles rising, which may happen if the container is not rigid and allows for convection currents to form, but does not accurately represent the behavior of particles within a rigid container. Box C shows the particles expanding, which is a possible result of the increased temperature, but does not accurately represent the movement of the individual particles within the container.
