Does hot air rise or fall?
Hot air rises
How does hot and cold air have an effect on an balloon?
If there is warm air in the balloon, cooler air makes the balloon rise and if there is cold air in the balloon warmer air makes the balloon fall.
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).
When hot and cold air meet the hot air rises to the top but which process causes the hot air to rise?
hot air rises because it is less dense than cold air..this occurs by the process of convection
Why does a hot air balloon rise in cold air?
The fire raises it not the heat of the temperature in the air that day. The wouldn't put a hot air balloon up when it was freezing cold or heaps windy.

Will a balloon rise higher with hot air or cold air?
Hot air

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).
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.
In which of these does hot material rise and cool material fall?
In a liquid (as solid particles in a liquid or in a lava lamp with two immiscible liquids) In the air, hot air rises, cold air descends (as in a hot air balloon)

Why does heat rise and how does cold drop?
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
Why do hot air masses rise over cold air masses?
Hot air has less mass which make it less dense, thus allowing it to rise over a cold air mass.
Hot air rises cold air sink?
technically hot air does not really rise it is the cold air that sinks below it because it is more dense.
How does hot air rise?
Hot air rises because it is less dense than cold air.
When hot and cold air meet the hot air rises to the top. Which process causes the hot air to rise?
Convection
