Weegy: A temperature of 20C C is equivalent to approximately 68 F.
User: How much heat energy is required to raise the temperature of 5 kilograms of coal from 20 degrees Celsius to 220 degrees celsius
Weegy: 1,314,718 J is 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 = 1314718 J.
