b. The water's temperature will increase a lot, and the metal's temperature will decrease slightly.
c. The water's temperature will decrease slightly, and the metal's temperature will increase a lot.
d. The water's temperature will increase by about the same amount as the metal's temperature decreases.
Answer:
Option A
Step-by-step explanation:
Given : A student heats 100 g of aluminum to 60°C. He places it in 100 g of water at 20°C.
To find : Over time, what will most likely happen?
Solution :
We know,
Heat will flow out of the warm aluminum and into the cool water.
The final "equilibrium" temperature will be a little less than 40°C (the average of 60° and 20°), because the specific heat of the aluminum is about 8% less than the specific heat of the water.
So when some quantity of heat flows from the aluminum to the water, the temperature of the water rises a little less than the temperature of the aluminum falls.
Therefore, Option A is correct.
The water's temperature will increase slightly, and the metal's temperature will decrease a lot.
