In the lab, you submerge 100 g of 40°C nails in 200 g of 20°C water. (The specific heat of iron is 0.12 cal/g # °C.) Equate the heat gained by the water to the heat lost by the nails, and show that the final temperature of the water is about 21°C.

Using the quantity of heat relation, the final temperature of water is

Given the Parameters :

Recall :

Heat lost by iron = Heat gained by water

Therefore the final temperature,

Final temperature of the mixture becomes

Explanation:

Here we know that heat given by the nail is equal to the heat absorbed by water

So here we know that heat to change the temperature is given as

so by equating the heat we have

now we have
