User: How much heat energy is required to raise the temperature of 5 kilograms of coal from 20°C to 220°C? A. 314 J B. 4,187,000 J C. 6,573 J D. 1,314,718 J

Weegy: 1,314,718 J of energy s required to raise the temperature of 5 kilograms of coal from 20°C to 220°C. Solution: Q = mcp(T2-T1); Q = 5kg (1.315 kJ/kg-K) (220 – 20); Q = 1,314,718 J.
