A 50 gram sample of delicious pork rinds is placed in an open, constant pressure calorimeter that contains 3000 grams of water. The temperature of the water increases by 47â—¦C when the pork rinds are combusted. The heat capacity of water is 4.184 J/g â—¦C. Assume the heat lost to the calorimeter itself or to the air is negligible. Which of the following is correct for the SYSTEM?
1. ∆U = −11.8 kJ
2. ∆H = +11.8 kJ
3. ∆U = +11.8 kJ
4. ∆H = +590 kJ
5. ∆H = −590 kJ
6. ∆H = −11.8 kJ
7. ∆U = −590 kJ
8. ∆U = +590 kJ

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
