is it posible to change the physl chracteristic of a substance by subjecting it to extremely high presure.why?

Answer 1

Yes, since compression will introduce stress to the material and will caues the particles comprising it to come together.

However, there are a lot of possible results:

1. An object changes into another form. Example, graphite, under extreme pressure becomes a diamond after a long time.

2. The object changes phase. Example, carbon dioxide, under extreme pressures, changes from a gas to a solid.

3. A simple change in shape. Dough changes shape when we exert pressure on ot.

4. Mechanical properties are changed. Concrete is stronger when compressed.

5. Electrical properties. Pressure gives quartz a net charge on each side that the pressures are acting on. Uncompressed quartz is electrically neutran.

So many more...

Answer 2

Yes it is possible

Under high pressures and low temperatures a gas can be converted in to liquid

This is because of the change in the cohesive forces between the atoms

Answer 3

It certainly is. Just think about what happens to high-temperature water vapor at high pressures. When you get far enough to the right of the triple point it's possible for the density of steam (water vapor) to exceed the density of liquid water by many times (mostly subject to real-world engineering constraints)

Answer 4

Yes it is...if the preassure is very high and constant and also has some assistance from heat.
Example: Carbon changing into diamond.

Answer 5

Have you eaver stepped on a snail? Did its physical characteristics change? There's your answer. Also, look up on how diamonds are made.

Answer 6

It's too costly to do this experiment so one tried it!
