The amount of heat that is spent on heating the body can be calculated using the following formula:
Q = C * m * Δt, where C is the specific heat of the taken substance (reference value), m is the mass of the taken substance, Δt is the change in the temperature of the substance.
The change in temperature and the mass of substances are equal, therefore, a substance with a higher heat capacity will require more heat when heated.
C1 (water) = 4200 J / (K * kg); C2 (copper) = 400 J / (K * kg).
Answer: Water will require more heat.
