WebYou can also freeze pure water by putting it into a vacuum. Water will boil when the vapor pressure exceeds the ambient pressure, and in a vacuum, this is the case at all … 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.

WebFeb 6, 2024 · For example, freezing would be an exothermic reaction, as heat energy is released (causing the molecules to condense); this, of course, would be the opposite of melting. Condensation is the opposite (reverse reaction) of vaporization, as gas turns to a liquid. This, too, is an exothermic reaction. Hi there!

WebTherefore ΔH is negative - freezing is an exothermic process (ΔH fusion = – 6 kJ/mol.) However freezing is also a process that reduces the system entropy. When water molecules are constrained, as in ice, their positional entropy is reduced.
