Question

Find the dimensions of the coefficient of linear expansion α and

Answer 1

Coefficient of linear expansion,
\[\left[ Q \right] = {\left[ {ML}^2 T^{- 2} \right]}$ \text{ and } \left[ T \right] = \left[ K \right]\]
\[So, \left[ C \right] = \frac{\left[ {ML}^2 T^{- 2} \right]}{\left[ M \right] \left[ K \right]} = \left[ L^2 T^{- 2} K^{- 1} \right]\] 
So, \[\left[ \alpha \right] = \frac{\left[ L \right]}{\left[ LK \right]} = \left[ K^{- 1} \right]\]
