Question

the pressure P of an enclosed gas held at a constant temperature is inversely proportional to the volume V of the gas Express P in terms of V and the constant of variation K . calculate 1)the value of K when P =500 and V = 2 2) the value of P when V =5​

Answer 1

(1) K = PV

K = 500*2

K = 1000

(2) PV = K

PV =1000

P*5=1000

P=1000/5

P = 200
