As a sample of water is heated, the energy is used to overcome the attractions between the molecules so that they are no longer
held close together and can move in random directions. Then, the kinetic energy of its molecules increases. Which sections of the heating curve illustrate this process?

Answer : The correct option is, (a) No. Potatoes will be warmer.
Explanation :
Formula used :
where,
Q = heat taken
m = mass of substance
c = specific heat of substance = ?
= change in temperature
As we are given that the potatoes have a specific heat of and raisins have a specific heat of
. That means higher the value of specific heat the more heat taken by the substance (more warmer will be the substance). So, the potatoes will be more warmer as compared to raisins.
Hence, the correct option is, (a) No. Potatoes will be warmer.
