In a calorimetry experiment, 169 g of zinc is taken from boiling water and dropped into 240 g of water, initially at 29.7oC. If no heat escapes to the surroundings, what is the final temperature of the system? answer in Celsius
HINT: No heat is lost to the surroundings, so the magnitude of heat Qhot that flows from the zinc is equal to the magnitude of heat Qcold
that flows into the water—that is, Qcold=Qhot
(Equation 13.3.2). Use Q=mc|ΔT|
Q=mc|ΔT| for each term and solve for the final temperature.
