Question

4. Prolonged exertion (exercise) for one hour in the hot sun burns 2700 kJ. We will consider this the internal energy. a. If 80% of the internal energy is converted into heat, how much energy (in kJ) does that account for?

b. What happens to the other 20%?

c. What mathematic expression do you use to relate internal energy to the different components?

Answer 1

Through First Law is thermodynamics, Internal Energy is related to heat (q) and (w) Work --{The other components }.
