4. A piece of metal weighing 59.047 g was heated to 100.0 °C and then put it into 100.0 mL of water initially at 23.7 °C).
The metal and water were allowed to come to an equilibrium temperature, determined to be 27.8 °C. Assuming no heat
lost to the environment, calculate the specific heat of the metal. (Hint: First calculate the heat absorbed by the water
then use this value for "Q" to determine the specific heat of the metal in a second calculation)
