A rock of mass 0.309 kg falls from rest from a height of 23.4 m into a pail containing 0.444 kg of water. The rock and water have the same initial temperature. The specific heat capacity of the rock is 1880 J/kg C°. Ignore the heat absorbed by the pail itself, and determine the rise in temperature of the rock and water in Celsius degrees.

A 218 kg rock sits in full sunlight on the edge of a cliff 5.05 m high. The temperature of the rock is 31.7 ∘C. If the rock falls from the cliff into a pool containing 5.90 m3 of water at 16.5 ∘C, what is the final temperature of the rock-water system? Assume that the specific heat of the rock is 1010 J/(kg⋅K).

An insulated aluminum calorimeter vessel of 150 g mass contains 300 g of liquid nitrogen boiling at 77 K. A metal block at an initial temperature of 303 K is dropped into the liquid nitrogen. It boils away 15.8 g of nitrogen in reaching thermal equilibrium. The block is then withdrawn from the nitrogen and quickly transferred to a second insulated copper calorimeter vessel of 200 g mass containing 500 g of water at 30.1 degrees celsius. The block coolds...
