Solution :
Formula used :
where,
Q = heat gained = 299 cal
m = mass of copper = 52 g
c = specific heat of copper =
= final temperature = ?
= initial temperature =
Now put all the given values in the above formula, we get the final temperature of copper.
Therefore, the final temperature of the copper is,
