Step 1

The specific heat capacity for a given substance refers to the amount of heat that is needed to raise the temperature of a given substance per unit of its mass. The relationship between specific heat capacity, mass, change in temperature and the heat of the solution is given by the following equation:

Step 2

In this problem, it has been given that the mass of the sample of lead is 15 g.

The change in temperature is given to be from 25oC to 215oC which can be calculated as follows:

Step 3

The specific heat capacity of the sample of lead is given to be 0.128 J/g oC
