Question
A 130.3 g piece of copper (specific heat 0.380 J/g °C) is heated and
then placed into 400.0 g of water initially at 20.7 °C. The water
increases in temperature to a final temperature of 22.2 °C. What is the
initial temperature (in °C) of the copper? (The specific heat of water is
4.184 J/g °C).

A 90.0 g piece of metal, initially at 98.6 °C, is placed into 120.0 g of
water initially at 24.3 °C. If the final temperature of the water is 34.0
°C, what is the specific heat of the metal? (The specific heat of water
is 4.184 J/g °C).
