Explain the terms melting, solidification, vapourisation and condensation.
Answers
Explanation:
Melting : the substance changes back from solid to the liquid.
condensation: the substance changes from a gas to a liquid.
vaporisation: the substance changes from a liquid to a gas.
solidification: the substance changes liquid into a solid state by colling .
Answer:
Melting: Melting is a process that causes a substance to change from a solid to a liquid. Melting occurs when the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid.
Solidification:Solidification is the process when a molten liquid becomes a solid. In the solidification of water to ice without sublimation, there is an increase in volume. The temperature fell slowly during the cooling until solidification of the melt began to take place.
Vapourisation :Vaporization can be defined as the process in which liquid state changes into the vapour state. As a result of an increase in temperature, the kinetic energy of the molecules increases. As a result, they escape into the surrounding in the form of vapours. ...
Condensation:Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
