What else can I help you with?
Does hot and cold air fall or rise?
Hot air rises and cold air falls.
What kind gas is used in hot air balloon?
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
Does hot air expand and rise?
yes
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
Will a balloon rise higher with hot air or cold air?
Hot air
Why would heating the gas in balloon make the balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Does heat rise or hot air rise?
Hot air rises. As air is heated, it becomes less dense and therefore more buoyant, causing it to rise. This is due to a difference in temperature creating a temperature gradient, leading to the movement of air.
What does hot air rise due to?
i
Does hot and cold air fall or rise?
Hot air rises and cold air falls.
When hot and cold air meet the hot air rises to the top. Which process causes the hot air to rise?
Convection
How does hot air rise?
Hot air rises because it is less dense than cold air.
Why does cold or hot air rise?
Cold air is denser than hot air, so it is heavier and sinks while hot air is lighter and rises. This movement is known as convection, where the warmer air displaces the cooler air, causing it to rise.
What kind gas is used in hot air balloon?
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
Does hot air expand and rise?
yes
What does air do at the equator?
Mostly get hot and rise.
