MATTER CAN CHANGE ITS STATE!!!

Mainly the states of matter depends upon two factor:-

• The first one is temperature and second one is pressure.

 

1.     Affect of temperature on states of matter:-

• If you heat to the solid its get convert into liquid and if you provide more and more heat to the liquid its get converted into gas.
• If you cool the gas the gas converted into liquid and if you cool more and more its converted into solid.

For example:-

• If you provide heat to the ice it converted into water and if you provide more and more heat to the water it converted into water vapour.
• If you cool the water vapour it converts into water and if you cool more and more the water gets converted into ice. 

2. Affect of pressure on state of matter:-

• If you provide more pressure on gas it will converted into liquid .

For example:- L.P.G

• Some gases can be converted into solid directly by providing high pressure.

 Example :- solid CO₂

• When you decrease the pressure of solid CO₂ its directly converted into gas without coming in liquid state.
• For storage of Solid   CO₂ we need high pressure.
• The change of state from solid to liquid is called melting or fusion.
• The change of state from liquid to gas is called vaporization.
• The change of state from gas to liquid is called condensation.
• The change of state from liquid to solid is called solidification.
• The change of state from solid to gas is called sublimation.
• The change of state from gas to solid directly is called sublimation.
