What will happen to the balloon stretched over the top of this empty bottle when the bottle is placed in hot water?
Hot Air Balloons The same thing happens if you stretch a balloon over an empty bottle, then stick that bottle in a bowl of hot water. It is not the water, but the heat in the water that is causing the balloon to inflate.
What happened to the balloon after attaching it to the mouth of the bottle?
When a balloon is placed inside the bottle, it will not inflate, since the bottle is already filled with air particles with no escape route. If the hole in the bottle is then plugged, the balloon stays inflated even when the mouth is removed.
What happened to the balloon after pouring the hot water into the container?
In hot water, the Balloon inflated because of hot air molecules, and in cold water, the Balloon deflated because of cold air molecules. The hot air molecules are less dense in weight and tend to rise and occupy more space. That’s the reason the hot air molecules travel inside the Balloon and make it expand.
What happens to a balloon when 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.
What happens when an inflated balloon is inserted to the mouth of the bottle?
They are pushed out as a balloon fills the space inside, resulting in room for the balloon to inflate. If the hole in the bottle is then plugged, the balloon stays inflated even when the mouth is removed. The air pressure in the bottle increases and collapses the balloon.
What happens to the air pressure inside the bottle surrounding the balloon as you suck the air from the hole of the bottle?
The balloon gets back to its original shape because it is made of rubber. In step-5, when you suck the air inside the bottle through the hole using your mouth, the air particle move out of the bottle slowly. This creates pressure inside the balloon. This pressure sucks the outside surrounding air particles in to it.
What will happen to the balloon when it is placed over the opening of a container filled with boiling water?
When you stretch the balloon over the opening of the bottle, all of the air is trapped inside. Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space (thermal expansion), causing air to enter the balloon and inflate it.
