Question

for a given mass of a gas ,if pressure is reduced to half and its temperature is doubbled ,then volume v will become

Answer 1

Answer:

Pv= nRT

Initial mole = final mole.

Let initial pressure =P1,

initial temperature=T1,

initial volume =V1.

Final pressure=P1/2.

Final temperature=2T1.

Final volume =V2.

Now,

P1×V1/T1 = P1/2×V2/2T1.

V2=4V1.

Therefore,final volume=4×initial volume.
