Answer:
28.16 °C
Explanation:
Considering that:-
Heat gain by water = Heat lost by metal
Thus,
Where, negative sign signifies heat loss
Or,
For water:
Mass = 165 g
Initial temperature = 28 °C
Specific heat of water = 4.184 J/g°C
For metal:
Mass = 4.00 g
Initial temperature = 75 °C
Specific heat of water = 0.600 J/g°C
So,
<u>Hence, the final temperature is 28.16 °C</u>
