Answer: The initial temperature of the iron was
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of iron = 360 g
= mass of water = 750 g
= final temperature =
= temperature of iron = ?
= temperature of water =
= specific heat of iron =
= specific heat of water=
Now put all the given values in equation (1), we get
Therefore, the initial temperature of the iron was
