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

The heat transferred (Q) can be calculated using the formula Q = mcΔT, where m is the mass, c is the specific heat, and ΔT is the change in temperature. Convert the mass to grams (8,000 kg = 8,000,000 g) and the specific heat to J/g°C (0.215 cal/g°C = 0.215 * 4.184 J/g°C). The temperature change ΔT is 10°C. Plug these values into the formula to find Q = 8,000,000 g * 0.215 * 4.184 J/g°C * 10°C = 7.2 × 10^7 J.
