# Mini-Quiz: Pressure in Fluids

by Ron Kurtus (revised 13 March 2016)

Take this Mini-Quiz to check your understanding of the lesson material.

14.7 pounds per square inch

There is no pressure inside the skull

There is no brain inside my skull

2. Why do your ears sometimes pop when flying in an airplane?

Increased air pressure at high altitudes cause the popping

Cheap headsets cause them to pop

Your body is compensating for the decreased air pressure

3. What would happen if you put a balloon in the refrigerator?

It would get smaller due to increased internal pressure

It would get larger due to reduced internal pressure

It would get smaller due to reduced internal pressure

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Be able to perform under pressure
