The equation you need for this problem is:
Q = (mass)( spec. heat)(change in temp)
Q = (5,000 g)(spec. heat of coal)(200 degrees C)
I don't know the specific heat of coal so you will need to check your text for this information.
The answer will be in units of joules.

If you can tell me the heat capacity of coal, then I will tell you the answer. The heat capacity is a number which tells you how much energy it takes to change a given amount of something by a degree C.
So the units will be joules / Deg C / kg
