Question

5L of air at 750mm mercury pressure were compressed into an iron cylinder of 1 litre capacity what will be the new pressure in atmosphere if the temperature remains constant

Answer 1

Explanation:

V1= 5 ml

P1= 750mm

750/760 atm

V2 = 1 litre

P2 = ?

P1V1= P2V2

P2 = P1V1 / V2

P2 =( 750 /760 × 5 ) / 1

P2 = 4.93 atm
