The correct answer is:
Heated gases will increase in kinetic energy and decrease in density.
Heated gases will increase in kinetic energy and decrease in density.
The correct answer is: Heated gases will increase in kinetic energy and decrease in density.
When gases are heated, the average energy of the gas molecules increases. This leads to an increase in their kinetic energy, which is the energy associated with their motion. As the gas molecules gain more kinetic energy, they move faster and collide more frequently with each other and with the walls of the container.
As a result of these collisions, the gas molecules exert a greater outward pressure on the walls of the container. This increase in pressure causes the gas to expand and occupy a larger volume.
At the same time, the increase in kinetic energy of the gas molecules causes them to move more vigorously and more randomly. This disrupts the ordered arrangement of the gas molecules and makes the gas less dense. In other words, the heated gas becomes less tightly packed as its molecules move apart.
Since the heated gas has a lower density than the surrounding cooler gas, it experiences a buoyant force. This buoyant force is directed upward, opposing the force of gravity. As a result, the heated gas rises to the top of its container.
So, in summary, heated gases increase in kinetic energy and decrease in density, which causes them to rise to the top of their container.
