1.	When two substance A and B of same mass are heated under similar conditions number of free surfaces have been found to reduce to zero from one. If A maintains constancy in the temperature for a longer time than B during heating , then
Answer» LATENT HEAT of FUSION of A is more than that of B. latent heat of vapourisation of A is more than that of B latent heat of fusion of B is more than that of A. latent heat of vapourisation of B is more than that of A. Answer :B::C
