Give some examples to show that physical state of matter can be changed by changing pressure ?
pls write right answer please
who give right answer then I gave 50 points him.

Step-by-step explanation:
All matter can move from one state to another. It may require extreme temperatures or extreme pressures.To create a solid, you might have to decrease the temperature by a huge amount and then add pressure. For example, oxygen (O2) will solidify at -361.8 degrees Fahrenheit (-218.8 degrees Celsius) at standard pressure. However, it will freeze at warmer temperatures when the pressure is increased.
the N² is nitrogen from the atmosphere in a liquid form and it has to be super cold to stay a liquid. To solidify liquid nitrogen you could increase the pressure in a sealed chamber. Eventually you would reach a point where the liquid became a solid. If you have liquid water (H2O) at room temperature and you wanted water vapor (gas), you could use a combination of high temperatures or low pressures to change the state of water
