1.a In the laboratory a student uses a "coffee cup" calorimeter
to determine the specific heat of a metal.
She heats 18.7 grams of chromium
to 98.51°C and then drops it into a cup containing
84.8 grams of water at 24.15°C.
She measures the final temperature to be
25.94°C.
Assuming that all of the heat is transferred to the water, she
calculates the specific heat of chromium to be
J/g°C.
1.b An electric range burner weighing 660.0
grams is turned off after reaching a temperature of
494.1°C, and is allowed to cool down to
22.1°C.
Calculate the specific heat of the burner if all the heat evolved
from the burner is used to heat 550.0 grams of
water from 22.1°C to
82.6°C.
Answer J/g°C
