A waterfall is 98 m high. What is the temperature change in the water due to its drop over the falls? Assume no heat loss to the surroundings.
A 70.0 g mass of brass at 70.0 degrees Celsius is placed in 110 g of water at 5.0 degrees Celsius. The water is in a copper calorimeter that has a mass of 55 g. What is the final temperature of the mixture?
A brass ball of mass 1.5 kg is dropped from a height of 35 m. If 50 percent of the heat generated stays in the ball, what will the temperature rise of the ball be?
