When a copper ball is heated,which of the following will show the maximum percentage increase?

$A$ thin copper wire of length $L$ increases in length by $1\%$ when heated from temperature $T_1$ to $T_2$. What is the percentage change in area when a thin copper plate having dimensions $2L \times L$ is heated from $T_1$ to $T_2$?

The moment of inertia $I$ of a uniform rod about a perpendicular bisector increases to $I+\Delta I$,if the temperature is increased slightly by $\Delta T$. If the coefficient of linear expansion is $\alpha$,then $\frac{\Delta I}{I}$ is (Assume $\frac{\Delta T}{T} \ll 1$)

When a bimetallic strip is heated, it

$A$ meter scale made of steel reads accurately at $25^{\circ} C$. Suppose in an experiment an accuracy of $0.06 \,mm$ in $1 \,m$ is required, the range of temperature in which the experiment can be performed with this meter scale is (Coefficient of linear expansion of steel is $11 \times 10^{-6} /{ }^{\circ} C$)

Write the relation between the coefficient of linear expansion $(\alpha_l)$,coefficient of area expansion $(\alpha_A)$,and coefficient of volume expansion $(\alpha_V)$.
