Overview

Engineering reference data for Freezing Points Liquids in miscellaneous.

Key Formulas

Unit Conversion

$y = x \cdot k$

Multiply by conversion factor.

Linear Interpolation

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

Percentage

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.

Freezing Points of Common Liquids

The following table provides freezing or melting points (at 1 atm) for a selection of common liquids. For a pure substance, these points are identical; for mixtures, ranges exist.

Pure Substances vs. Mixtures

For a pure substance, the melting point and freezing point are identical at a given pressure.

For a mixture (e.g., petroleum), there is a range of melting/freezing points. The initial melting point is close to the melting point of the lightest component, while the initial freezing point is close to the freezing point of the heaviest component. This is why, for petroleum mixtures, the initial freezing point is greater than the initial melting point.
