The apparent coefficient of expansion of liquid when heated in a copper vessel is c and when heated in a silver vessel is s .If A is the linear cofficient of expansion of copper then the linear cofficient of expansion of silver is :

S safeer

\gamma _{r}= \gamma _{app}+\gamma _{vessel}

for copper;\gamma _{r}= c+3\: \alpha _{cu}=c+3A

for silver; \gamma _{r}= c+3\: \alpha _{Ag}=s+3\: \: \alpha _{Ag}

\Rightarrow c+3A=s+3\: \: \alpha _{Ag}

\: \alpha _{Ag}= \frac{c+3A-s}{3}
