Question

A cylinder with a movable piston contains 3 moles of hydrogen at standard temperature and pressure. The walls of the cylinder are made of a heat insulator, and the piston is insulated by having a pile of sand on it. By what factor does the pressure of the gas increase if the gas is compressed to half its original volume?

Answer 1

according to the law (p1*v1)/t1=(p2*v2)/t2
where v1 and p1 are equal to initial volume and pressire amd p2 and v2 are equal to final pressure and volume but the temprature remains the same
so
p1*v1=p2*v2
p1*v1 =p2*(v1/2)
p2=2*p1
