The relationship between pressure and the melting point
Thread Content
What is the relationship between material pressure and the melting point? Is there any chart available? Please let me know
Hehe, I don’t know anything else, but when water turns into ice, the greater the external pressure, the lower the freezing point.
Reply to 3# tf176: No basis
Material pressure has little to do with the freezing point
It doesn’t really matter; there’s a similar curve simulation diagram available in Cambridge
Reply to 6# vrain: The original poster might still need to go back and review the books on physical chemistry. The question posed by the original poster can be understood as the effect of pressure on the crystallization point. For a pure substance, it refers to the effect of pressure on the freezing point. There is a statement in the textbook on physical chemistry that the equilibrium pressure for solid-liquid equilibrium changes with temperature to a much greater extent than that for solid-gas and liquid-gas equilibria. In other words, in solid-liquid equilibrium, even a slight change in temperature can lead to a significant change in the equilibrium pressure. In other words, relatively speaking, pressure changes have little effect on the freezing point.
It depends on the temperature. If the temperature of a substance is higher than its critical temperature, it will not liquefy even under high pressure, let alone solidify. Under normal circumstances, however, pressure has little effect on the freezing point; the freezing point is largely determined by the properties and composition of the substance
