You use a mixer to vigorously stir water in a bowl. The mixerdoes 2643.83 J of work on the water. The bowl, however, is not wellinsulated, and 1177.19 J of heat escapes the water through the bowlduring the mixing process. What is the total internal energy change(in J) of the water after mixing? Round your answer to two decimalplaces. (Hint: Consider the signs of both work and heat in thecontext of the problem.)
