(120,0) -20 0 100 200 300 600 700 800 400 500 AQ/m (calg) a. Segment 2 and Segment 4 depict| b. Use the graph calculate the specific heat of water. Specific heat of water = cal/(g°C)

1. In a study of healthy young men, doing 20 push-ups in 1 minute burned an amount of energy that for a 70-kg man corresponds to 8.06 kcal. How much would a 70-kg man's temperature rise if he did not lose any heat during that time? Assume that the specific heat of the human body is 0.83 kcal/(kg °C) AT= V°C
