Let p = pressure. 1. - latent heat of fusion, T = melting point temperature, `V_2` = volume of solid state and and `V_1` = volume of liquid state. Then, which of these are correct regarding melting point of a solid?

A

`(dp)/(dT)=L/(T(V_2-V_1))`

B

when `V_(2) gtV_(1)`, then`(dp)/(dT)gt -0` and melting point increases with increase in pressure

C

when `V_(2) lt V_1` then `(dp)/(dT)lt 0` and melting point decreases with increase in pressure

D

Melting point of all solids does not vary with pressure
