If we continue to heat the water we will begin to observe bubbles form and collapse on the bottom of the beaker. These are the precursors to true boiling. The water on the bottom surface of the beaker is heated to the point where it converts to vapor, but this vapor cools rapidly as ...

Why does water have a higher boiling point compared to ethanol? Why are group 1 melting points and boiling points lower than those of group 2 elements? What causes a substance to have a low boiling point? What is the effect of impurities on boiling point?

Keywords: superheating; microwave; reflux; temperature; boiling point 1. Introduction Accurate temperature measurements are critical to understanding thermochemical processes. While this can be easily done for conventional convective heating using thermometers and thermocouples, it is not so easily done under...
The boiling point is defined as the temperature at which the vapor pressure of a liquid equals the surrounding atmospheric pressure. Physically this means that enough energy must be supplied to overcome any intermolecular interactions that may be occurring in the liq...
