Charles Law • The volume of a fixed mass of a gas is directly proportional to its Kelvin temperature if the pressure is constant temp volume V1= V2 T1 T2
Example If a sample of gas occupies 6.80L at 325°C what will its volume be at 25°C if the pressure doesn’t change?
Guy-Lussac’s Law • The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant. temp pressure P1 = P2 T1 T2
Example A sample of nitrogen gas has a pressure of 6.58kPa at 539K. If the volume does not change, what will the pressure be at 211K?
