An aluminum tea kettle of 0.45-kg containing 2.40-kg of water at
25°C is placed on a
burner. Assuming that the burner is rated at 2000 Watt, how long
will it take to bring
the water to a boil? (b) Once boiling begins, how much time is
required to boil all the
water out of the tea kettle? Assume that no energy is lost in this
process.

Steam at 100°C is condensed into a 54.0 g copper calorimeter cup containing 280 g of water at 25.0°C. Determine the amount of steam (in g) needed for the system to reach a final temperature of 64.0°C. The specific heat of copper is 387 J/(kg·°C). 4231.29 Be sure to account for the heat energy absorbed by the calorimeter cup and the water in the cup, and the heat energy contributed by the steam. Note that the steam contributes heat energy...
