Is it possible that an object of any state of matter does not change its state of matter no matter how much we heat, freeze or apply pressure on it?

Solution

All matter exists as solids, liquids, or gases. These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. When water is cooled it will become solid.
If water is heated, it changes to steam (a gas). This change is calledBOILING. The particles of ice, water, and steam are identical, but arranged differently.
The increase in pressure changes the state of matter
from gas to liquid and also from liquid to solid. But increase in pressure alone cannot change the state of matter. Every gases and liquid have certain temperature above which the application of pressure would not change the state of matter.
