Question
Three perfect gases at absolute temperatures T1, T2 and T3 are mixed. The masses of molecules are m1, m2 and m3 and the number of molecules are n1, n2 and n3 respectively. Assuming no loss of energy, the final temperature of the mixture is :
Options
A.
B.
C.
D.
Solution
Data ⇒ n1T1k1 + n2kT2 + n2kT3 = (n1 + n2 + n3) kT
∴
∴
