Heated gases will increase in kinetic energy and decrease in density.
The correct response would be:
Heated gases will decrease in density.
When gases are heated, the molecules gain energy and their kinetic energy increases. As a result, the molecules move faster and collide more frequently with each other and with the walls of the container. These collisions create pressure within the gas.
As the gas heats up, the average distance between the molecules increases, causing the gas to expand and the density to decrease. The hotter the gas, the greater the expansion and the lower the density.
Since the cooler gases in the container are denser than the heated gases, they exert a greater downward force. This creates a pressure gradient where the denser, cooler gas pushes the less dense, heated gas upwards. Consequently, the heated gases rise to the top of the container.
