Weegy: Heat from burning fuel warms the walls of the firebox section of the furnace in a hot-air heating system. 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. (More)

Weegy: Heat energy is required to raise the temperature of 5 kilograms of coal from 20 degrees celsuis to 220 degrees celsius is 1,300,000 J . [ q = m*C*(deltaT) ,q = (5 kg)(1.3 kJ/(kg*degC))(200 degC) , q = 1,300 kJ = 1,300,000 J ] (More)
