Using the following information to answer the question.
A student performed a calorimetry experiment and recorded the following data.
Mass of aluminum calorimeter 470.0 g
Mass of the calorimeter water 100.0 g
Specific heat of aluminum 0.900 J/gC
Specific heat of water 4.184 J/gC
initial temperature of calorimeter water 23.0 C
final temperature of calorimeter water 24.6 C
Mass of silicon 52.0 g
initial temperature of silicon 61.6 C
Calculate the amount of energy lost or gained by the silicon in the experiment?

Heat gained by Al = 470.0 g (0.900 J/gC) (24.6-23) = 677 J
Heat gained by H2O = 100.0 g (4.184 J/gC) (1.6C) = 669 J
Heat gained by calorimeter and water = 1346 J
Heat lost by Si = -1346 J
(If this is the final answer, you should round this to 2 significant figures because your temperature change for the water is only 1.6 C.)
