Expert Solution

Step 1

Heat absorbed or released by a substance is calculated as:

$q = m . C . ∆ T$

m is the mass of the substance,

C is the specific heat capacity,

$∆ T$ is the change in temperature.

Given:

mass of substance = 42.0 g

Rate of heating = 100 J/min

From the chart, liquid phase exist from C to D in the time interval 7-11 minutes. The temperature in this interval goes from 10^oC to 80^oC
