Hey user, here is your answer...
___________________________________
Write a short note on interconversion of states of matter.
A short note on interconversion of states of matter is:-
▶️There are basically 3 states of matter.
▶️They are solid, liquid and gas.
___________________________________
On application of heat:-
▶️On increasing the temperature of solids, the kinetic energy, of the particles increases.
▶️Due to the increasing kinetic energy the particles start vibrating with greater speed.
▶️The energy supplied by heat overcomes the forces of attraction between the particles.
▶️The particles leave their fixed position and start moving more freely.
▶️A stage is reached when the solid melts and is converted to a liquid.
▶️Similarly, when we supply heat energy to water, particles start moving even faster.
▶️At a certain temperature, a point is reached when the particles have enough energy to break free from the forces of attraction of each other point.
▶️At this temperature the liquid starts changing into gas.
___________________________________
Process of Sublimation.
➡️We know that substances around us change state from solid to liquid and from liquid to gas on application of heat.
➡️But there are some that change directly from solid state to gaseous state and vice versa without changing into the liquid state.
➡️Increasing or decreasing the pressure can change the states of matter.
___________________________________
Effects of change of Pressure.
✔️By applying pressure and reducing temperature we can liquefy gases.
✔️For Example:- Solid Carbon Dioxide( CO2 ) is stored under high pressure.
✔️Solid CO2 gets converted directly to gaseous state on decrease of pressure to '1 atmosphere' ( is a unit of measuring pressure ) without coming into liquid state.
✔️Thus, we can say that 'pressure' and 'temperature' determine the state of a substance, whether it will be solid, liquid or gas.
