9. A 20.0-g piece of metal at 203°C is dropped into 100.0 g of water at 25.0°C. The water
temperature rises to 29.0°C. Calculate the specific heat of the metal (J/gºC). Assume that all of the heat lost by the metal is transferred to the water and no heat is lost to the surroundings.
10. Assuming no heat loss by the system, what will be the final temperature when 50.0 g of water at 10.0°C is mixed with +25.0 g of water at 60.0°C?
11. Three 500.0-g pans of iron, aluminum, and copper are each used to fry an egg. Which pan
fries the egg (105°C) the quickest? Explain.
12. At 6:00 P. M., you put a 300.0-g copper pan containing 800.0 mL of water (all at room
temperature, which is 25°C) on the stove. The stove supplies 628 J/s. When will the water reach
the boiling point? (Assume no heat loss.)
