The mass of water vapor contained in a certain volume of air

Question 22

Differential Pressure

Answer 22

The difference between pressures being read at two different locations within a system

Question 23

Boyles’ Law

Answer 23

The volume of an enclosed dry gas varies inversely with its absolute pressure, provided the temperature remains constant
Volume 1 x Pressure 1 = Volume 2 x Pressure 2

Question 24

Charles’ Law

Answer 24

Volume 1 x Absolute Temperature 2 = Volume 2 x Absolute Temperature 1
