A balloon is tied to a rock and dropped into the ocean. What will happen to the volume of the balloon?
Hint: As you get deeper into the ocean, the pressure increases
The volume will decrease

Before a rock is placed in a graduated cylinder, the volume of water in the cylinder is at 32.3 ml. After the rock is placed in the graduated cylander, the volume is 35.6 ml. If the mass of the rock is 17.16 g, what is the rock's density?
5.2 g/ml

In a hot air balloon, fuel is ignited, causing the air around it to heat up. The hot air is then directed into a large balloon, and the balloon begins to rise. Why does the balloon rise in terms of gas laws?
Hint: Think about the density of the gas
As the air heats up, it becomes less dense. Eventually the air in the balloon will be less dense than the air outside of the balloon, causing it to rise.
