Class 9- Study of Gas Laws

Boyle's law states the relation:

• P/V = k

• V/T = k

• PV = k

• VT = k

Charle's law states the relation:

• P/V = k

• V/T = k

• PV = k

• VT = k

Convert 20⁰ C to Kelvin

• 290 K

• 293 K

• 300 K

• None of the above

Boyle's law formula for solving numericals

• P1V1 = P2V2

• P1/V1 = P2/V2

• V1T1= V2T2

• V1/T1 = V2/T2

Charles's law formula for solving numericals

• P1V1 = P2V2

• P1/V1 = P2/V2

• V1T1= V2T2

• V1/T1 = V2/T2
