An 8 000-kg aluminum flagpole 100-m long is heated by the sun from a temperature of 10°C to 20°C. Find the heat transferred (in J) to the aluminum if the specific heat of aluminum is 0.215 cal/g⋅°C.

Question

Quizplus · Accepted Answer

The heat transferred can be calculated using the formula Q = mcΔT. The mass (m) is 8,000,000 g, the specific heat (c) is 0.215 cal/g°C, and the temperature change (ΔT) is 10°C. Converting calories to joules (1 cal = 4.184 J), the heat transferred is 7.2 × 10^7 J.
