mass

Question 2

True or False. According to Charles’s Law, if you have a balloon inside a car at noon during a hot summer day, the molecules inside of the balloon will cause the volume of the balloon to increase.

Group of answer choices

True

False

Question 3

Name the gas law. Volume and pressure are indirectly proportional. Volume will decrease if pressure increases, and volume will increase if pressure decreases.
