Web20 dec. 2024 · The fluid around the cells, but not in the cells, is frozen solid. As water freezes outside the cell, water from within the cell is drawn out through osmosis. Osmosis is a process in which water moves across a semipermeable membrane—in this case, the cell membrane—from an area of low solute concentration to an area of high solute … WebIf the reverse process, freezing the water to ice, is to occur, the water has to lose that enthalpy. So freezing one mole of liquid water to ice has an enthalpy change of -6.00 kJ. Incidentally, as you can see, enthalpy and other thermodynamic changes depend a great deal on the phases of the reactants and products in a thermochemical equation. chuanchengfanpaipaohuixiongchonghou

Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled. But this can be understood since heat must be continually removed from the freezing liquid or the freezing process will stop.
