Hot and Cold Balloon Experiment

You won't believe your eyes as you attach a balloon to an empty bottle and place it in hot water! The balloon will quickly expand and begin to inflate thanks to the air heating up and creating higher air pressure inside.

The exact opposite will happen if the balloon and bottle are placed in cold water as the balloon will deflate.

This hot and cold balloon experiment is a super fun and easy way to teach kids about how high and low pressure/hot and cold temperatures work!

This is a super fun and easy experiment to do at home with just a few simple supplies:

Empty Water Bottle
Balloon
Bowl of Hot Water
Bowl of Ice Water

The science behind this experiment:

As the bottle with the balloon attached is placed in hot water, the air inside the bottle heats up and the molecules move around faster and increase the volume and air pressure enough to inflate the balloon.

Then as the bottle is moved back into the cold water, the air molecules lose energy and slow down. They don't bounce around as quickly and the volume and pressure decrease as the balloon deflates.

this is gay lussac's law, right? when the bottle heats up from the hot water- the pressure increases causing for the balloon to inflate. oppositely, when the bottle is placed on the cold water, the pressure decreased causing for the balloon to shrink

hot excites the particles and causes it to expand as its a gas and cooling it stabilizes the particles hence the sink

[Dhruigg]

what was the temperature of the hot and cold water?

[adriannahernandez]

How would I put the information in a graph or table format

Thank u for showing our experiment I need to find ballon now heheh

Just to let you know, Im the 700th comment :)

hot rises and cold sinks...physics is KEKW

[victoriaaguilar]

what is the constant variable of this experiment?
what is missing from this experiment ?(think about the 5 components)
describe the change in the state of matter seen as the temperature changed
why does the balloon begin to expand as the bottle is placed over the hot water?
would the boiling point of the water change if I increased the sample size of water? explain your answer.

From the experiment, describe the relationship of the volume and temperature of a gas?

What explanation would you give to your experiment
