What else can I help you with?
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
What happens to volume and mass in a hot air balloon?
When the air is heated inside the balloon, it expands, causing it to be lighter than the surrounding (and presumably) cooler air. One imagines however, that as the air inside the balloon is heated, some air is forced out (due to expansion), thus resulting in a decrease in the entire apparatus' overall mass (not to mention a decrease in mass due to any fuel's having been used to heat the air in the balloon).
Does heated magma rise or sink?
When magma is being heated it rises. When it is cooled, it sinks.
What are some examples of lighter than air vehicles?
-- blimp -- Zeppelin -- dirigible -- hot-air balloon
Are paint solvent vapors lighter than air?
Yes, paint solvent vapors are typically lighter than air, which causes them to rise and disperse into the surrounding environment. This property can lead to an increased risk of inhalation exposure in poorly ventilated areas.
Heated air that is lighter than surrounding air will do what?
Heated air that is lighter than surrounding air will rise, as it is less dense. This process creates convection currents, with cooler air moving in to replace the rising warm air.
Heated air that is lighter than the surrounding air will?
rise upwards because it is less dense. As the heated air rises, it cools, becoming more dense, and eventually will fall back down once its temperature is similar to the surrounding air. This process is known as convection.
What happen to air when heated it will move up or down?
When air is heated, it becomes less dense and therefore lighter than the surrounding cooler air. This lighter, warm air will rise because of the buoyant force. Conversely, when air is cooled, it becomes denser and therefore heavier, causing it to sink.
Why heated gas become lighter?
because..................................................................................................................... density of heated gas is lower than cooled gas.
Which of these is a lighter than air craft?
Without having the information about what the options are there really is not any way to know which is lighter than aircraft. The rest of the information needs to be provided for the correct answer to be given.
Why does heat rise?
Heat rises because when a substance is heated, its molecules gain energy and move faster, causing them to spread out and become less dense. This decrease in density makes the heated substance lighter than the surrounding cooler air, causing it to rise.
Why does heated air arise?
Cause its lighter than room temperature air..
What are the gases on a hot air balloon?
Hot air balloons are typically filled with hot air, which is lighter than the surrounding cold air, allowing the balloon to float. They do not contain specific gases, other than the air heated to lift the balloon.
Is a hot air balloon lighter or heaver then air?
A hot air balloon is lighter than air because the air inside the balloon is heated, which causes it to become less dense than the surrounding air. This buoyant force allows the balloon to float in the air.
How does heat cause a hot air balloon to rise?
When air inside the balloon is heated, it becomes less dense and lighter than the surrounding cooler air. This lighter air creates a buoyant force that causes the balloon to rise. As the air inside cools down, the balloon will begin to descend.
What happens to copper oxide when its heated?
if it is heated above 1200 degrees celsius than it melts
What happens to a hot air balloon that allows it to float through the air?
Air inside the balloon is heated. Hot air is less dense than the surrounding air, and thus the balloon rises.
