⚠️ Common Exam Traps & Conceptual Pitfalls

Students often forget that expansion coefficients are defined as a *fractional* change per unit temperature, i.e., $\alpha=\frac{1}{L}\frac{dL}{dT}$ and $\beta=\frac{1}{V}\frac{dV}{dT}$, so both have dimensions of $K^{-1}$. Treating them as having length or volume dimensions leads to the wrong conclusion.

Consider the following statements. A) The coefficient of linear expansion has dimension

K^{-1}

. B) The coefficient of volume expansion has dimension

K^{-1}

Multiple Choice Options
