1.) 1g of iron at 130°F are mixed with 50g
water at 55°F. What is the temperature
of the mixture? (ciron=0.11 cal/g°C).
2.) 300g of water at 50°C in a 100g glass
are added to 20g of ice at 0°C. Solve for
the final temperature of the mixture.
Assume that the ice has melted.
(Cglass=0.16 cal/g-°C)
3.) 30g of steam at 100°C are cooled to
form water at 60°C. How much heat is
liberated?
