A 220-lb athlete drinks a glass of soda (125 calories) and walks up to the top of a Library Building. What is the change in his internal energy, assuming the only heat transfer is the 125 calories from the soda drink, and the only work done by the athlete is lifting his own weight to the 6th floor? Assume 3m per floor.
A system does 1.80×108 J of work while 7.50×108J of heat transfer occurs to the environment. What is the change in internal energy of the system assuming no other changes (such as in temperature or by the addition of fuel)?
In a game of football outdoors on a cold day, a player will begin to feel exhausted after using approximately 8.0 x 10 J of internal
energy. (a) One player, dressed too lightly for the weather, has to leave the game after losing 7.0 x 10° Jof heat. How much work has he
done? (b) Another player, wearing clothes that offer better protection against heat loss, is able to remain in the game long enough to do

- By jogging, a girl is converting food energy into internal energy at the rate of 399 kcal/h above her basal metabolic rate (BMR). Some of this additional internal energy immediately goes into work done at a rate of 56.1 W.
