Three liquids with masses m1,m2,m3 are thoroughly mixed. If their specific heats are c1,c2,c3 and their temperatures are T1,T2,T3 respectively, then the temperature of the mixture is:
Given, T1,T2 and T3 are the temperature of liquids with mass m1,m2 and m3 with specific heats c1,c2 and c3
Let the final temperature be T∘C.
Total heat supplied by the three liquids in coming down to 0∘C is
Total heat used by three liquids in raising temperature from 0∘CtoT∘C is
By equating (i) and (ii) we get,
