Question

a cylinder with a movable Piston content 3 mole of hydrogen at standard temperature and pressure the wall of the cylinder are made of heat insulator and the Pista is insulator by having a pile of sand on it by what factor does the pressure of the gas increases the gases compressible to half its original volume ​

Answer 1

let internal volume of the gas in the cylinder V

V1=V2

V2=V/2

P2/P1=?

hydrogen is a diatomic gas

Y= 7/5=14

for an adiabatic change

p1v1=p2v2

p2/p1=(v1/v2)^Y

=2.64

Answer 2

Explanation:

let internal volume of the gas in the cylinder V

V1=V2

V2=V/2

P2/P1=?

hydrogen is a diatomic gas

Y= 7/5=14

for an adiabatic change

p1v1=p2v2

p2/p1=(v1/v2)^Y

=2.64

hope this helps you
