Benzoic acid, C6H5COOH, melts at 122 °C. The density in the liquid state at 130 °C is 1.08 g/cm3. The density of solid benzoic acid at 15 °C is 1.266 g/cm3. (b) If you converted a cubic centimeter of liquid benzoic acid into a solid, would the solid take up more, or less, volume than the original cubic centimeter of liquid?

Hi everyone, so ask. Given the following values for acetic acid, we have the melting point, the density below the melting point as a solid and the density above the melting point as a liquid. And I ask which statement is true if one mL of liquid acetic acid is converted to solid in the same mass of a compound, the sample with the higher density will occupy the smaller volume. The salt has a higher density than the liquid, so the density of the solid is greater than the density the liquid, so the volume the solid, it's less than the volume of the liquid. The answer is going to be a look at phase. We have a larger volume than the solid phase. Thanks for watching my video and I hope it was helpful.
