Answer : The final temperature is,
Explanation :
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of water at
= 150 g
= mass of water at
= 100 g
= final temperature = ?
= temperature of lead =
= temperature of water =
= same (for water)
Now put all the given values in equation (1), we get
Therefore, the final temperature is,
