Question

Define melting, melting point, freezing freezing point, evaporation , sublime , sublimation

Answer 1

Explanation:

Melting point

The temperature at which a given solid will melt.

Freezing point

The temperature at which a liquid freeze.

Sublime

In aesthetics, the sublime (from the Latin sublīmis) is the quality of greatness, whether physical, moral, intellectual, metaphysical, aesthetic, spiritual, or artistic. The term especially refers to a greatness beyond all possibility of calculation, measurement, or imitation.

Evaporation

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.

Sublimation

Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.

Answer 2

Answer:

• Melting: Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point.

• Melting point : The melting point of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.

• Freezing : Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling.

• Freezing point : the temperature at which a liquid freezes.

• Evaporation : Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.

• Sublime : elevated or lofty in thought, language, etc.: Paradise Lost is sublime poetry. impressing the mind with a sense of grandeur or power; inspiring awe, veneration, etc.: Switzerland has sublime scenery.

• Sublimation : Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.
