A solid object of mass M is made of material of specific heat
Question

A solid object of mass M is made of material of specific heat capacity c, latent heat of fusion L and of very high thermal conductivity. When the object enters the atmosphere from outer space, its temperature below its melting point by ΔT. Because of atmospheric friction, it absorbs energy at a constant rate of R. The time before the solid becomes completely molten is

A
M(C+L)ΔTR

B
M(CΔT+L)R

C
M(C+L)ΔTR

D
R(MΔT(C+L)
