What is Boyle's law?

State the definition of the law in words.

What are the assumptions of Boyle's law?

Write at least one mathematical equation that represents the law.

What can be calculated with Boyle's law?

Using a gas-filled balloon as an example, describe what is happening to the gas molecules inside the balloon before and after you squeeze it.

Boyle's law is a gas law stating that pressure is inversely proportional to volume. The assumptions of this law is that the conditions of the gas must be ideal with a fixed temperature and there must be no changes in the amount of gas molecules. One mathematical equation using the Boyle's law is P1V1=P2V2. Pressure and volume can be calculated using Boyle's law. Squeezing the balloon will increase the pressure and the volume will decrease.
