Question 1

boyles law

Answer 1

the volume of a fixed amount of gas at a constant temp is inversely proportional to the pressure

(P1V1 = P2V2)

Question 2

charles law

Answer 2

the volume of a fixed amount of gas at a constant pressure is directly proportional to its absolute temperature

(V1/T1=V2/T2)

gay-lussac’s law

Answer 3

the pressure of a given amount of gas held at constant volume is directly proportional to the temperature

(P1/T2=P2/T2)
