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. 6,573 j c. 1,314,718 j d. 4,187,000 j

C. 1,314,718 J

Explanation:

The heat energy needed to raise the temperature of the coal is given by:

where:

m = 5 kg is the mass of the coal

is the specific heat of coal

is the increase in temperature

Substituting into the formula, we find

So, the closest option is

C. 1,314,718 J
