100 g of water and 100 g of iron are heated up to the same temperature and are separately added to 50 g of water at a lower temperature, kept in two identical vessels. Compare the temperature changes in the two vessels.

100 g of water and 100 g of iron are heated up to the same temperature

1.	100 g of water and 100 g of iron are heated up to the same temperature and are separately added to 50 g of water at a lower temperature, kept in two identical vessels. Compare the temperature changes in the two vessels.
Answer» Solution :TEMPERATURES of both the vessels will increase. Specific heat of iron is much less than that of WATER `(s_("water")=1 and s_("iron")=0.117)`. The initial temperature of the given specimens of 100 g of water and 100 g of iron are equal. But, due to its higher specific heat, water will lose more heat than iron will. HENCE, the final temperature of the vessel in which 100 g of HOT water is added will be higher.
