A 209 kg rock sits in full sunlight on the edge of a cliff 5.45 m high. The temperature of the rock is 29.6 ∘C.
If the rock falls from the cliff into a pool containing 5.10 m3 of water at 17.7 ∘C, what is the final temperature of the rock-water system? Assume that the specific heat of the rock is 1010 J/(kg⋅K).
Homework Answers
After falling through height temperature of rock will slightly increase.Then heat lost by rock will be equal to heat gained by rock.
