Why does a balloon get bigger when it is warmed up?
Air molecules collide into the balloon with the same energy inside and outside the balloon. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.
Does a balloon get bigger when heated?
When heat is supplied, air molecules get higher kinetic energy and move rapidly, thus causing an expansion of the air mass and hence the balloon. Hope this helps. A balloon gets larger when it is heated due to thermal expansion. This mostly has to do with the energy of the molecules inside the balloon.
What do you think will happen to the balloon if the water is heated?
When you put the bottle with the balloon into the first jar, the hot water heats up the air in the bottle and makes it expand. The expanding gas blows up the balloon. When you put the bottle into cold water, the air cools down again. Cool air hasn’t got as much energy, so it shrinks – and the balloon shrinks with it.
What happen to the size of the balloon as the temperature decreases?
The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Why does the balloon gets inflated in hot water?
Explanation: The hot water causes the air inside the bottle and balloon to also heat up. The faster moving particles inside the bottle start to move faster and faster and soon they expand to fill the balloon.
Why do we heat the balloon?
We do not really heat the balloon, rather we heat the air inside it. Air heats up and since hot air is lighter than ambient cold air, it rises and causes the balloon to expand. The lighter the balloon gets (due to hot air inside), the higher it rises and when we release the hot air, the balloon descends.
What happens to the size of a balloon when it’s filled?
However, once you’ve filled the balloon, it should stay the same size; this is because the average energy of the molecules inside the balloon “pushing” on it from the inside, is equal to the energy from the outside. When you heat up the balloon, you add energy to the molecules inside.
Why does a balloon inflate when the density is high?
When the density of air is high, the air pressure is high. The pressure of the air pushes on the balloon from the inside, causing it to inflate. If you heat the balloon, the air pressure gets even higher.
What happens to a balloon when the temperature decreases?
This happens because the air inside the balloon occupies a smaller volume when the temperature is decreased, thus causing the walls of the balloon to collapse. Air is a gas and has molecules that are free to move around inside a closed container with a certain amount of energy.
