3.Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered to or below its freezing point. ... Most liquids freeze by crystallization, the formation of a crystalline solid from the uniform liquid.
4.Sublimation is the conversion of a substance from the solid to the gaseous state without its becoming liquid. It occurs more frequently among substances that are close to their freezing point. Sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid.
5.At a certain temperature, the particles in a liquid have enough energy to become a gas. The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation.
6.The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. ... Therefore, we define the normal boiling point as the temperature at which a liquid changes to a gas when the surrounding pressure is exactly 1 atm, or 760 torr.
