In this article Change of states of matter, you will be going to learn deeply about the changes in states of matter and also the terms involved in change in the state of motion.
In daily life, we will come across various substances also like solid, liquid and gas. Example water, wax and ghee, etc.
Water is the common example that exists as ice(solid), water(Liquid)as well as water vapour(gas).
Interconversion of change in state of matter
The phenomenon in which the change of matter from one state to another and to its original form by altering the condition of temperature and pressure is the Interconversion of states of matter.
There are two factors that make it possible to change the state of matter.
- change in temperature
- Change in pressure.
Terms involved in change of states.
- Fusion or Melting and melting point.
- Boiling and Boiling point
- Sublimation
- Vapourisation
- Freezing and Freezing point
- Condensation.
Fusion or Melting and Melting point.
The process of conversion from solid to liquid state because some conditions of temperature and pressure are fusion or melting.
So, a definite temperature at which a solid starts to melt is its melting point.
Boiling and Boiling point
The process of conversion of metal from its liquid state to vapour (or) gaseous state because some conditions of temperature and pressure are boiling.
So, the temperature at which a liquid starts boiling at the atmospheric pressure is the boiling point.
Sublimation
The process in which solid-state change into the gaseous state without passing through a liquid state is Sublimation And also the direct change of gas to solid without changing into liquid is the deposition.
Vapourisation
The process of converting liquid state to gaseous state also at the specific conditions at temperature and pressure is vapourisation.
Freezing and Freezing Point
The process of conversion of matter from a liquid state to a solid-state and also with the specific condition of temperature and pressure is freezing. The reverse process is fusion or melting.
The temperature at which between changes into solid-state by giving out heat energy is called freezing point.
Condensation
The process of conversion of the gaseous state becomes liquid because of some specific condition of temperature and pressure is called condensation. The reverse process is called vapourisation.
