When 1 gm of water at 0oC and  1×105N/m2 pressure is converted into ice of volume 1.091cm2 , the external work done will be

a
0.0091 joule
b
0.0182 joule
c
– 0.0091 joule
d
– 0.0182 joule

detailed solution

Correct option is A

It is an isothermal process. Hence work done =P(V2−V1)=1×105×(1.091−1)×10−6=0.0091J
