1.	As a physicist, you put heat into a 500 g solid sample at the rate of `10.0 kJ//min`, while recording its temperature as a function of time. You plot your data and obtain the graph shown in figure. . (a) What is the latent heat of fusion for this solid? (b) What is the specific heat of solid state of the material?
Answer» Correct Answer - A::B::C::D (a) Between `t = 1 min` to` t = 3 min`, there is no rise in the temperature of substance. Therefore, solid melts in this time. `L = Q/m = (HT)/m = (10 xx2)/0.5` `=40kJ//kg` (b) From `Q = msDeltaT or s = Q/(mDeltaT)` Specific heat in solid state `s = (10 xx 1)/(0.5 xx 15) = 1.33 kJ//kg-^@C`
