A heated piece of metal at a temperature T1 is placed into acalorimeter containing water and a stirrer. The temperature of thecalorimeter, water, and stirrer is initially T2 where T1 > T2.The system is stirred continuously until it comes to equilibrium ata temperature of T3.
(Pick one)
1. The final equilibrium temperature of the system is suchthat
T3 > T1 > T2
T1 < T2 < T3
T1 < T3 < T2
T1 > T3 > T2
(Pick one)
2. The heat lost by the metal ?Qm and the heat gained by thecalorimeter system ?Qc obey which of the followingrelationships?
?Qm > ?Qc
?Qm < ?Qc
?Qm = ?Qc
3. What is the purpose of stirring the system continuously?
