Question

Please give your own examples of solids, liquids, and gases: A Molecular Comparison. Below you will find key questions on this topic.

1. Define crystalline and amorphous and recognize the difference in solids.
2. Know that both temperature and pressure can affect phase changes.

Answer 1

So for the examples of solid liquids and gases we just have to look around us and we can classify everything in solid liquid and gases by just looking at it

Solids - chair, rock, wood, glass

Liquids - water, petrol, juice etc

Gases - oxygen, carbon dioxide, water vapores, etc

Now question 01.

Crystalline and amorphous

By defination crystalline solids are - solids whose Constituents are arranged in highely orderd way.

And anorphous solids are whose Constituents are not arranged in ordered way.

There are various difference in these solids as

Now question 2

Yes the temperature as well as pressure both affect the phase changes in any element or compound

And this can be studied using phase diagram where we study the phase of that substance at various temperature and pressure

I hope this helps if you have any query or want more detailed explanation feel free to ask in the comments section below. ​​​​​​
