A

The volume of a gas and it’s pressure are inversely proportional.

16
Q

The volume of a gas and it’s pressure are inversely proportional.

A

Bottles law

V is proportional to 1/P

17
Q

Boules law mathematical formula

A

V=(constant/P)

18
Q

Charles law

A

The volume of gas increases proportionally as it’s kelvin temperature increases

19
Q

Charles formula

A

V=Constant*T

V1/t/1)=(V2/T2

20
Q

Combined gas law

A

(P1V1/T1)=(P2V2/T2)

Applies when amount of gas is constant
Must use kelvins

21
