Question

explain with an activity with respect to the interconversion of solid state to gaseous state and vice versa without changing into liquid State class 9th chemistry chapter 1​

Answer 1

Answer:

Vaporization of an element or compound is a phase transition from the liquid phase to vapor.

Boiling point is the temperature at which liquid changes to vapor. Examples: Boiling of water.Water changes to water vapor at 100 0

C which is melting point of water.

Freezing, or solidification, is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point.Freezing point is the temperature at which liquid changes to solid

Liquid water turning to ice is an example of freezing.

Freezing point of water is 00c

Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.

The temperature at which a given material changes from a solid to a liquid, or melts is called as its melting point. Example : Ice melts at 32 o

Fahrenheit or 0

0 Celsius
