We put 50 g of ice of 0 °c in a beaker containing 450 g of beer of 20 °c, mix, and wait for heat exchange within the beaker. what will be the final temperature?

Answer : The final temperature will be, 292 K

Explanation :

In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.

where,

= specific heat of ice =

= specific heat of beer =

= mass of ice = 50 g

= mass of beer = 450 g

= final temperature = ?

= initial temperature of ice =

= initial temperature of beer =

Now put all the given values in the above formula, we get:

Therefore, the final temperature will be, 292 K
