pressure and temperature determine the state of substance .explain in detail
Answers
Explanation:
Any matter i.e., solid, liquid or gas when experiences an increase in temperature then they change their state.

Take ice cubes in a beaker or heat them slowly, the temperature increases and the ice melts to form liquid. Heat this liquid further it will become steam.
(2) On lowering down the temperature of any matter, show change in their state.

Take the steam that is coming out of a boiling water and allow it to cool down, it condenses to form water and on further cooling of this water we get ice.
(3) On applying pressure and reducing temperature we can liquefy gases or change them into solid.
Example: Take carbon-dioxide gas, reduce its temperature and apply lot of pressure on it so that it changes into solid carbon dioxide, called dry ice, which is used as refrigerant for cooling.
If the pressure on it is decreased it directly changes into gas.
In LPG cylinders, the petroleum gas is cooled and with lot of pressure changes it into liquid state.
While using this LPG, we release the pressure exerted on it and hence it comes out in the form of gas.
Pressure and temperature determine the state of substance.
Yes, the temperature and pressure are two factors that determines the state of matter.
Temperature :-
When the temperature of solid is increased the kinetic energy of particles also increased this lead to change the solid then liquid.
The decrease in temperature of a gas lead to change in liquid states then solid.
Solid + ∆ → liquid +∆ →Gases
where ∆ is temperature.
Pressure :-
The increase in pressure leads to the conversion of gaseous state in to liquid state.
There is no effect of pressure in liquid.
Gases + P → Liquid
where, p is pressure.
hence, we can say that both temperature and pressure change the states of matter.
