Heat capacity of the body = 400J / Kg. 0С, weight 5kg. when heated, it received 8 kJ of heat.

Heat capacity of the body = 400J / Kg. 0С, weight 5kg. when heated, it received 8 kJ of heat. determine the change in body temperature

Initial data: C (specific heat of the body) = 400 J / (kg * K), m (body weight) = 5 kg; Q (the amount of heat that the body received when heated) = 8 kJ = 8 * 10 ^ 3 J.

The change in body temperature (Δt) is expressed from the following formula:

Q = C * m * Δt and Δt = Q / (C * m).

Let’s make a calculation:

Δt = 8 * 10 ^ 3 / (400 * 5) = 4 ºС.

Answer: Body temperature has increased by 4 ºС.
