<u>Answer:</u> The final temperature of the solution is
<u>Explanation:</u>
The amount of heat released by coffee will be absorbed by aluminium spoon.
Thus,
To calculate the amount of heat released or absorbed, we use the equation:
Also,
..........(1)
where,
q = heat absorbed or released
= mass of aluminium = 39 g
= mass of coffee = 166 g
= final temperature = ?
= temperature of aluminium =
= temperature of coffee =
= specific heat of aluminium =
= specific heat of coffee=
Putting all the values in equation 1, we get:
Hence, the final temperature of the solution is
