A 10 lb. frozen boneless roast needs to be thawed and baked to a temperature of 200 degrees F.

The storage freezer maintains a temperature of -10 degrees F.

Pork changes from solid to a thawed state at 30 degrees F and has the following properties:

Heat Capacity "c" (frozen) = 0.50 BTU/(lb x F degrees)

"c" thawed = 1.2 BTU/(lb. x F degrees)

Heat of fusion (hf) = 125 BTU/lb.

How many BTUs does it take to bring the roast to a tasty 200 degrees F?
