Question

Heat is supplied to a certain homogeneous sample of matter at a uniform rate. Its temperature is plotted against time as shown in the figure. Which of the following conclusions can be drawn?

• A. its specific heat capacity is greater in the solid state than in the liquid state.
• B. its specific heat capacity is greater in the liquid state than in the solid state.
• C. its latent heat of vaporization is greater than its latent heat of fusion.
• D. its latent heat of vaporization is smaller than its latent heat of fusion.

Answer 1

Answer: (A), (C)

The correct options are
A its specific heat capacity is greater in the solid state than in the liquid state.
C its latent heat of vaporization is greater than its latent heat of fusion.

$t_1$ is more than $t_2$ (From graph)

Because $t_1$ is more it contains more heat acquired in it.

So, Specific capacity is greater in solid state than in liquid state.

$t_4$ is more than $t_3$ So, latent heat of vaporization is greater than its latent heat of fusion.
