Either.
Hot water causes the air inside the balloon to expand, increasing the pressure inside. This increased pressure pushes against the walls of the balloon, making it inflate and potentially burst if the pressure becomes too high.
The air pressure inside the balloon will decrease when placed in cold water, as the air molecules cool and move closer together. Conversely, the air pressure will increase when the balloon is placed in hot water, as the air molecules heat up and move further apart.
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
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.
A hot air balloon needs hot air to rise. In colder air, the balloon loses its buoyancy and cannot generate enough lift to stay airborne. Cold air is denser and heavier, which makes it harder for the hot air balloon to ascend.
Hot ice, also known as sodium acetate, can be used to blow up a balloon by creating a chemical reaction that produces carbon dioxide gas. Cold ice, on the other hand, will not blow up a balloon as it does not release any gas.
Hot water blows up a balloon because it is taking up space. Second, Hot water gives off extra gas to fill up a balloon quicker.
hot balloon will pop first
in Biology when u put yeast in test tube and put cold, hot, or warm water in it and put a balloon on top of it why does it blow up?
From your breath that is hot.
Cold water causes a balloon to deflate because the cold air the cold water releases is more dense than the hot air hot water releases. Take a hot air balloon for example, the flames cause the air in the balloon to heat up, causing the hot air balloon to rise. In order to make the balloon go down, you slowly turn on and off the flames in order to cool the air already inside the balloon over a period of time.All in all, cold waters causes balloons to deflate.P.S. Sorry if that made absolutely no sense, it's rather difficult explaining these types of things. c:

which term describes what happens to a cold balloon when placed in a hot car
She was Sandra Brennan.
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.
