Most Upvoted Answer
On heating, gases become ______ because the molecules ______.a)heavier...
Expansion of Gases on Heating
Gas molecules have more energy when heated, which causes them to move faster and spread out. This results in the gas expanding in volume.
Lighter
When gases are heated, they become lighter because the average kinetic energy of the molecules increases, causing them to move more quickly. This increased movement results in the gas occupying a larger volume, making it less dense.
Expansion
As the gas molecules gain energy and move faster, they push against their container's walls with more force, causing the gas to expand. This expansion is a result of the increased distance between the molecules as they move more freely in the container.
