Answer:Explanation:Given that the temperature of of water and of water are

at and respectively.

Let ,

and , .

The specific heat capacity of water is,

.

Let the final temperature of the mixture be .

As there is no energy loss, so, the energy loss by the water at higher temperature, i.e. , will be equal to the energy gain by the water at lower temperature, i.e. .

[ both sides divided by ]

Now, putting the given value in the above equation, we have

Hence, the temperature of the mixture will be .
