The correct answer is B. Sublimation<\/strong>.<\/p>\n Sublimation is the process of a substance changing directly from a solid to a gas without passing through the liquid state. This process is the opposite of deposition, which is the process of a gas changing directly into a solid.<\/p>\n Sublimation can occur when a solid is heated to a temperature below its melting point. At this temperature, the molecules of the solid have enough energy to escape from the solid state and enter the gas state. Sublimation can also occur when a solid is exposed to a vacuum. In a vacuum, there is no pressure to force the molecules of the solid to remain in the solid state. As a result, the molecules of the solid can escape from the solid state and enter the gas state.<\/p>\n Sublimation is a common process in nature. For example, snow and ice sublime on cold, dry days. This is why you may see snow or ice disappear on a sunny day, even though the temperature is below freezing.<\/p>\n Sublimation is also used in some industrial processes. For example, sublimation is used to dry food and to produce dry ice.<\/p>\n A. Deposition is the process of a gas changing directly into a solid. This process is the opposite of sublimation.<\/p>\n C. Melting is the process of a solid changing into a liquid. This process occurs when the temperature of the solid is raised to its melting point.<\/p>\n D. Condensation is the process of a gas changing into a liquid. This process occurs when the temperature of the gas is lowered to its condensation point.<\/p>\n E. Crystallization is the process of a liquid changing into a solid. This process occurs when the temperature of the liquid is lowered to its freezing point.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Deposition” option2=”Sublimation” option3=”Melting” option4=”Condensation E.
