Post by: cdr_15 on Aug 6, 2020: An 8 000-kg aluminum flagpole 100-m high is heated by the sun from a temperature of 10°C to 20°C. Find the increase in internal energy (in J) of the aluminum. (The coefficient of linear expansion is 24 × 10⁻⁶ (°C)⁻¹, the density is 2.7 × 10³ kg/m³, and the specific heat of aluminum is 0.215 cal/g⋅°C.)
