| Determine how many degrees the body heats up, having received 90 kJ of heat, if the body has a mass of 10 kg and is made of aluminum.
Initial data: Q (amount of heat received by the aluminum body) = 90 kJ = 90,000 J, m (mass of the aluminum body) = 10 kg.
Constants: C (specific heat capacity of aluminum) = 920 J / (kg * K).
We calculate the change in body temperature from aluminum from the formula:
Q = C * m * Δt and Δt = Q / (C * m).
Let’s do the calculation:
Δt = 90,000 / (920 * 10) = 9.78 ºС.
Answer: The aluminum body will heat up to 9.78 ºС.
