Problem
Two solid objects of the same mass are supplied with heat at the same rate ΔQ / Δt. The temperature of the first object with latent heat L₁ and specific heat capacity c₁ changes according to graph 1 on the diagram. The temperature of the second object with latent heat L₂ and specific heat capacity c₂ changes according to graph 2 on the diagram.
[Figure: Temperature vs Time graph showing two different heating curves]
Based on what is shown on the graph, the latent heats L₁ and L₂, and the specific heat capacities c₁ and c₂ in solid state obey which of the following relationships:
(a) L₁ > L₂ ; c₁ < c₂ ;
(b) L₁ < L₂ ; c₁ < c₂ ;
(c) There is not enough information to determine these relations;
(d) L₁ > L₂ ; c₁ > c₂ ;
(e) L₁ < L₂ ; c₁ > c₂ .
