(i) OA – Temperature of the solid in increasing;
AB- solid is melting;
(ii) Heat supplied = Heat gained
p x t = MC(change in temperature)
200 x 100 = 0.2 x C x 100
20 x 100 = 0.2 x C x (350 – 250)
C= 1000J/Kg/K.
(iii) Heat applied = heat gained; OR
p x t = Mlf; --->where lf is the latent heat of fusion.
200 x 200 = 0.2 x lf;
lf = 200,000J/Kg;
