Question 2

Boyle’s Law

Answer 2

At a constant temperature the volume of a gas is inversely proportional to its pressure

Question 3

Dalton’s Law

Answer 3

The total partial pressure of a gas is the sum of the partial pressure of the components of that gas or the pressure exerted by a specific atmospheric gas.
