Explanation:

Here the problem deals with the relationship between the amount of heat lost and the temperature change of a body.

From the relationship below:

        H  = m C Δt

H is the quantity of heat

m is the mass

C is the specific heat

Δt is the change in heat

  We can see that the quantity of heat is directly proportional to the Δt, so as more heat changes occur, so also is the value of Δt .
