Three objects of different materials but of equal masses are kept in a heating chamber where all three receive energy at a same constant rate. During heating each object starts with liquid state and finally gets converted in the gaseous state. For each of the object, temperature T versus time t graph is plotted, as shown and marked I, II and III.
I. If SI, SII, and SIII are their respective specific heats in liquid state then
A
SI>SII>SLii
B
SI>SlII>SI
C
SII>SI>SLii
D
SII>SI>SlI
Answer
SII>SI>SlI
Explanation
Solution
As H ∝ t and
is minimum for III thus minimum rise in temperature in the same time comparing with others, i.e. it has maximum specific heat.
