Homework 8 Objective 5

Objective 5:

1. Boyle's law states that when the volume goes up the pressure goes down and vice versa.
2. When you go up in elevation the pressure decreases. This lower pressure would cause the balloon to expand and burst if it was filled all the way. This is why high-altitude balloons are only filled half way.
3. Pressure x volume= constant.
4. When you breathe in and flex your diaphram, you are increasing the volume of your lungs (by breathing in) and then you increase the pressure by flexing your diaphram.
5. As the diver goes deeper into the water, the pressure increases. According to Boyle's law, of the pressure increases, volume will decrease. This is important to the diver because the diver's body has numerous air spaces.
