Answer : The final temperature of the metal block is,
Explanation :
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of aluminum = 55 g
= mass of water = 0.48 g
= final temperature = ?
= temperature of aluminum =
= temperature of water =
= specific heat of aluminum =
= specific heat of water=
Now put all the given values in equation (1), we get
Thus, the final temperature of the metal block is,
