Question

Help! I don't have the things to do this and its due TODAY! Could someone help me?

Pull a balloon over the mouth of a bottle, and put the bottle in a saucepan of cold water. Slowly
heat the water over a stove. What happens to the balloon?
Take the bottle out of the water and allow it to cool. Now what happens to the balloon?
Explain, using the terms:
• molecule
• heat
• expansion
• contraction

Answer 1

Answer:

--- The hot air inside the bottle creates an expansion and when the hot water is applied a contraction occurs, thus causing the balloon to be sucked.

--- An internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.

Explanation:

I hope I have helped with something.

Answer 2

When the bottle is placed into the pan of hot water, the heat from the water causes the air inside the bottle to heat up. As the air in the bottle heats up, the molecules of the air begin to move faster and take up more space. The air from the bottle then moves into the balloon causing it to inflate.

What is heat?

Heat is the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object.

The hot air inside the bottle creates an expansion and when the hot water is applied a shrink occurs, thus causing the balloon to be contract.

Internal pressure is produced, joining the heat begins to decrease. As a consequence, the air molecule causes the balloon to enter the bottle thanks to the effect of the external pressure.
