Unit 4

Question 1

Boyles law

Answer 1

V1P1=V2P2

Volume of a gas varies inversely with the pressure when temperature stays the same.

Question 2

Charle’s law

Answer 2

V1/T1=V2/T2

Volume of a gas varies directly with the temperature when pressure remains the same

Question 3

Gay-lussac’s law

Answer 3

P1/T1=P2/T2

Pressure varies directly with temperature when volume remains the same

Question 4

Combined gas law

Answer 4

V1P1/T1=V2P2/T2 or
V1 P1 T2=V2 P2 T1

Relationship shows directly proportional relationship between temperature and pressure and temperature and volume. Also the inversely proportional relationship between pressure and volume, when the amount of gas remains the same
