Question

12. Two samples have temperature as T1 T2 and their masses are mı and m2. If
two samples are mix with each other, what is the temperature of the mixtures?​

Answer 1

Explanation:

Let the specific heat of the substance be S.

Heat released by one part of substance is absorbed by other part of substance to attain equilibrium temperature T.

Total mass of substance, M=m

1 +m 2

Thus m 1 ST1+m2 ST2=MST

∴ m 1 ST1 +m 2ST2

=(m1+m2)ST

⟹ T= m1+m2m1T1+m 2T 2
