9. A 84.5 gram sample of speedskatium (c=0.266 J/g C) is heated with 499 Joules. If its starting
temperature is 21°C, what will its final temperature be?
10. How many grams of water (c=4.18 J/g-°C) can be taken from 4°C to 97°C if 2193 Joules are used?
11. A 33.54 gram steel nail (c=0.41 J/g-°C) is heated until it glows. It is then dropped into a cup with 103
grams of water (c=4.18 J/g-°C) at a temperature of 5.9°C. If the water and steel reach an equilibrium
temperature of 72.5°C, what was the hot temperature of the steel?
