Answer:
The final temperature is 20.3 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by brass
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 300.0 g
Initial temperature = 20.0 °C
Specific heat of water = 4.184 J/g°C
For brass:
Mass = 19.0 g
Initial temperature = 81.7 °C
Specific heat of water = 0.375 J/g°C
So,


<u>Hence, the final temperature is 20.3 °C</u>
