Jogging every day is good for health. Assume that when you jog a work of 500 kJ is done and 230 kJ of heat is given off. What is the change in internal energy of your body?

Text Solution

Verified by Experts

Work done by the system (body), W = +500 kJ
Heat released from the system (body), Q = -230 kJ
The change in internal energy of a body `= DeltaU=-230 kJ - 500 kJ = - 730 kJ`
