The transfer of energy as heat caused by the collision of molecules is called conduction, mathematically represented as $Q = -k A \frac{dT}{dx}$.

To solve $(3n \pm 5)2n$, simplify to $6n^2 + 10n$ for the positive case and $6n^2 - 10n$ for the negative case.

A solution of NaNO₃ with 120 g of solute in 100 g of H₂O at 50°C is best described as supersaturated since it exceeds the solubility limit of 114 g.

To determine the true proportion, cross-multiply each pair and verify if their products are equal; for the given examples, only $\frac{3}{8} = \frac{15}{40}$ is true.
