The total change in energy inside the balloon when it deflates can be calculated by subtracting the work done by the balloon to the surrounding air from the energy transferred to the outside.
Total change in energy = Energy transferred to the outside - Work done by the balloon
Total change in energy = 60kJ - 300kJ
Total change in energy = -240kJ
The total change in energy inside the balloon when it deflates is -240kJ.
A balloon of air deflated and does 300kj of work to the surrounding air. While deflating the air inside the balloon transfers 60kj of energy to the outside of the balloon. What is the total change of the inside the balloon when it deflates?
