I need to find the change in internal energy and and the number of nutritional calories consumed.?

this ignment, as well as the other six are meant to test your ability in physics, francis, not your ability to ask others online. i would appreciate if you worked out the problems yourself rather than stealing the answers from online. if you cannot complete these simple exercises, you will have great difficulty on the final exam, as there will be no short answer or multiple choice questions to boost your mark like the midterm. Im sure you would not have a ping grade unless I had used a bell curve to increase the average number of points on the exam. I am very disappointed francis.
