Answer: The final temperature of both the weight and the water at thermal equilibrium is .
Explanation:
The given data is as follows.
mass = 7.62 g,
Let us assume that T be the final temperature. Therefore, heat lost by water is calculated as follows.
q =
=
Now, heat gained by lead will be calculated as follows.
q =
=
According to the given situation,
Heat lost = Heat gained
=
T =
Thus, we can conclude that the final temperature of both the weight and the water at thermal equilibrium is .
