One kg of a substance (initially solid of `0^(@)C`) is supplied heat at a concentration of 2 kcal/min. suffificent of thermal expansion of the solid `(a)=4xx10^(-6)//.^(@)C` its temperature varies with increase shown.

which of the following is not correct?

Options

A. Melting point of the substance is `20^(@)C`
B. Boiling point of the substance is `110^(@)C`
C. Latent heat of vapourization for the substance is greater than the latent heat of fusion.
D. Specific heat capacity of liquid is more than that of the solid

Explanation

`& tantheta_(2)=4`
`(dQ)/(dt)=ms(dT)/(dt)`
Specific heat is inversely prooportional to `(dT)/(dt)` i.e. slope of T-curve as `theta_(2)` is for solid `& theta_(1)` for liquid `& tan theta_(2)lttantheta_(1)`
`therefore s_("solid")gts_("liquid")`
