Question

3. The tank of an air compressor contains gas at normal atmospheric pressure ( 1atm). If the compressor motor pumps the equivalent of three extra tanks of air into the compressor tank, what will be the final pressure?

Answer 1

Answer:

Explanation:

pv = nrt

here volume of tank remains constant and number of moles increases

therefore p α n

let initial number of moles be n. the pump pumps 3n into the tank

total no of moles = 4n

p/n = Pₓ/4n

Pₓ = 4 p
