1. (a) what name is given to the law describing the relationship between volume and pressure at constant temperature? write a mathematical expression that describes this relationship. (2 marks)
(b) sketch a graph of the relationship described in part (a).

Explanation:

a) Boyle's law states that pressure is inversely proportional to the volume of the gas at constant temperature.  

(At constant temperature)

The equation given by this law is:

where,

are initial pressure and volume respectively.

are final pressure and volume respectively.

b) A graph of the relationship is attached as an image.

it is a solid
