Question

How much should the pressure be increased in order to decrease the volume by 5% at constant temperature

Answer 1

as temperature remains constant we can apply Boyle’s Law, 
the law can be usefully expressed as P₁V₁ = P₂V₂.

V₂ =0.95 V₁ (as V₂ is 5% less than V₁)

P₁×V₁ = P₂×V₂

P₁×V₁ = P₂ (0.95×V₁)

P₂ = P₁/ 0.95

P₂ = 1.052 P₁





% Increase in pressure = 5.2
