The coefficient of apparent expansion of a liquid when determined using two different vessels A and B are γ1 and γ2 respectively. If the coefficient of linear expansion of vessel A is α, the coefficient of linear expansion of vessel B is
A
αγ1γ2γ1+γ2
B
γ1−γ22α
C
γ1−γ2+α3
D
γ1−γ23+α
Solution
γreal=γapp+γvessel;γvessle=3α
ForvesselA =γreal=γ1+3α
ForvesselB =γreal=γ2+3αB
Hence, γ1+3α=γ2+3αB
⇒αB=γ1−γ23+α
