The specific heat of a substance in the solid state is C1; its specific beat in the liquid state is C2 and its latent heat of fusion is L. If a mass M of the substance is changed from the solid state at temperature T, to the liquid state, also at temperature T, the amount of heat required will be
-
A.
M(C1 ÷ C2) x T -
B.
ML -
C.
L -
D.
M(C1 + C2) × T ÷ ML -
E.
ML(C1 + C2 ÷ 2) × T
