Suppose a woman does of work and of heat transfer occurs into the environment in the process.

(a) What is the decrease in her internal energy, assuming no change in temperature or consumption of food? (That is, there is no other energy transfer.)

 

(b)

The internal energy is stored energy due to food intake. Treating the change in internal energy as the input energy and work done as output, what is her efficiency?
