This video explains how gas pressure changes as volume changes. Pressure and volume are inversely proportional. That means if the volume of a gas doubles, its pressure halves for a fixed amount of gas ...

This video explains how pressure in a fluid increases as the depth increases. At a particular point in a fluid, we can calculate the pressure, measured in Pascals. The pressure caused by a column of ...

This video explains the differences between contamination and irradiation. Contamination is when a radioactive material ends up somewhere it shouldn’t be. Irradiation is when a person or object ...
