When a liquid is heated in a glass vessel, its coefficient of apparent expension is `1.03xx10^(-3)//^(@)C.` When the same liquid is heated in a copper vessel, its coefficient of apparent expansion is `1.006xx10^(-3)//^(@)C.` If the coefficient of linear expension of copper is `17xx10^(-6)//^(@)C,` then the coefficient of linear expansion of glassA. `8.5xx10^(-4)//^(@)C`B. `9xx10^(-6)//^(@)C`C. `27xx10^(-6)//^(@)C`D. `10xx10^(-4)//^(@)C` |

Answer» Correct Answer - B Here, `gamma_(r)=gamma_(ag)+3alpha_(g)=alpha_(ac)+3alpha_(c)` `rArr1.03xx10^(-3)+3alpha_(g)=1.006xx10^(-3)+3xx(17xx10^(-6))` `alpha_(g)=9xx10^(-6)//""^(@)C` |
