The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.

Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
Do heated air particles become more or less dense?
Things (almost everything, including air) becomes less dense when it is heated. So warm air rises, and cold air falls.
What is the name of the process by which air moves and carries heat energy?
Convection is the process by which heated air (or any fluid) rises within the same medium because of its decreased density, then sinks again as it cools.
What is the meaning of convection?
The air/liquid heats up causing it to rise at the top it cools down causing it to sink. At the bottom it rises again because it heated then it rises up causing it to sink because it has cooled down. The pattern will go until the heat is stopped.

When the land gets hot it heats the air above it the heated air rises because it?
because its evaporating
Why air rises when it is heated?
No
What replaces heated air at the equator?
Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Why are cooling pipes at the top of fridges?
Simply, because that is where the warmest air is, inside a refrigerator. Air rises as it's heated, as heated air is less dense than cold air.
Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
Why is the air in a heated room usually cooler near the floor than the ceiling?
because hot air rises and cold air sinks.
Convection occurs because heated material becomes what?
Convection occurs because heated material becomes less dense and rises, while cooler, denser material sinks. This creates a circular motion of fluid or air to transfer heat.
Why a spoon is getting heated over a fire?
A spoon over a fire would would be heated from convection, because convection is when hot air rises and cold air falls which is known as a convection current.
What happen when air gets heated?
As air (unconfined), is heated its volume increases, and its density decreases. That makes it lighter (per volume) than it was. Warm air will rise above colder air, and in essence, float on top of the colder air.
Why do hot air balloon rise up?
because the density in the balloon is heated so it rises higher than it being unheated
Warm air rises because of its?
the warm air rises because of its Kinetic energy !
What do the word updraft mean in science for the tornadoes?
It is when heated air rises quickly.
