Question

the pressure of a gas p(v) varies inversely with the volume of the gas v. The pressure of a gas measure 15 kg/cm2 when its volume 300 cm3
p(v)=20v
p(v)=20/v
p(v)=4500v
p(v)=4500/v

Answer 1

Fisrt establish the equation of the pressure p

Since pressure varies inversely with the volume v

P ~1/v

P = k /v

And solve for k

K = PV

K = 15 (300)

K = 4500

So

P(v) = 4500 / v

Answer 2

Answer:

p(v)= 4500/v
