1. A closed container is filled with water at 15oC and at atmospheric pressure. Calculate the increase in pressure when the container is heated to raise the water temperature is increased to 45oC.

Solution

volume is constant

therefore P₁/P₂ =T₁/T₂

GIVEN P₁=1atm =101.325KPa T₁= 15^OC =288K

T₂= 45^OC =318K

THEREFORE P₂=(T₂/T₁)*P₁

P₂ =111.88KPa
