Explanation:
VAPOURISATION - DEFINITION
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 - DEFINITION
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 0
0
C
SUBLIMATION - DEFINITION
Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.
MELTING POINT - DEFINITION
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.
VAPORISATION - EXAMPLE
Conversion of liquid state in the gaseous state in water is called vaporisation.
INTERCONVERSION OF THREE STATES OF MATTER - DIAGRAM
CHANGE OF STATE OF MATTER - DEFINITION
1. States of matter are inconvertible by applying Heat and pressure to them.
2. When solids are heated the inter molecular force of attraction between particles decreases and they converts into liquids.
3. Liquids on further heating converts into gases .
4. Gases are invisible , do not have any fixed shape and volume because inter molecular force of attraction become zero.
INTERCONVERSION OF MATTER - DEFINITION
The state of matter are inter convertible. The state of matter can be changed by applying pressure and temperature .
SUBLIMATION - DEFINITION
The change from solid state to vapour state without passing through the liquid state is called sublimation and the substance is said to sublime. Dry ice (solid CO
2
) and iodine sublimes.
Answer:
Sublimation is the transition of a substance directly from the solid to the gas state,[1] without passing through the liquid state.[2] Sublimation is an endothermic process that occurs at temperatures and pressures below a substance's triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid. The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.[3] Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition (deposition).[4] While a transition from liquid to gas is described as evaporation if it occurs below the boiling point of the liquid, and as boiling if it occurs at the boiling point, there is no such distinction within the solid-to-gas transition, which is always described as sublimation.
