The foam seems to form a layer of insulation that allows the sap to reach a higher temperature to increase the rate of evaporation. It happens with any protein product when boiling, like beans and other legumes besides meat. For a vapor bubble to expand, the temperature must be high enough that the vapor pressure exceeds the ambient pressure (the atmospheric pressure, primarily).Below that temperature, a water vapor bubble will shrink and vanish. A pot of hot water will rapidly boil with a lid, in this case a layer of foam, while an uncovered pot will barely form bubbles at the bottom of the pot. Instead, choose a large pot and add no more than 2 cups of water for every cup of rice -- although brown rice requires a little extra.

Posted by krist on 16 April 2017, 10:43 pm. We guess the boiling point of water is lowered by the addition of the instant coffee granules, but this does not make sense in light of your explanations about a solute RAISING the boiling point of the solvent. This foam is water-soluble protein released from the peas and it will be absorbed back into the cooking liquid. When there’s a leak in the cooling system, the pressure of the liquid drops and so does the boiling point of the coolant/antifreeze. Now, if we continue to heat the water it will reach boiling point, which is about 100℃ (at sea level). First, the liquid on the bottom of the pot closest to the heat source starts to get hot; as it does, it rises. Boiling & Steam. These air bubbles come to the surface of the boiling water and appear as foam. Learn an ingenious tip to prevent the foam in the pot from boiling over. The foam is generally scooped off.
