The amount of heat required to change the temperature of a material from T1 to T2 is given by Q= mCp(T2-T1). Using this equation, answer the following: a. How many BTU’s of heat are required to cook a beef roast weighing 10 lb from 40 to 130oF?, Cp = 0.8 BTU/lboF b. Convert the number of BTU’s of heat in watt hours. c. If this roast is heated in a microwave oven having an output of 200 watts, how long will it take to cook the roast?
