Question

why there is no equation of state for the solid or liquids compounds ?

Answer 1

What do you mean by equation of state? im confused

Answer 2

gas law ? PV= n RT
why not solid or liquid law ?

Answer 3

Because the gas molecules expands as the temperature increases (Thats why there is volume in the equation). In the other hand, solids and liquid particles "stick" together more than the gases. Hope this helps :)

Answer 4

good attempt @Thee121 but not satisfied :)

Answer 5

Alright :) At least i tried...

Answer 6

Solid materials are formed from densely-packed atoms, which interact intensely.
Atoms may be arranged in a regular, geometric pattern or irregularly.
And Solid and Liquid doesn't change volume when compress by pressure (unless it deformed).

Answer 7

They haven't been discovered yet, I think it's because of the small distance between the particles and deformations the objects would get.

Answer 8

We use thermal expansion equations to describe changes of materials due to temperature and they properties

Answer 9

any thoughts @DLS

Answer 10

Solids don't contribute to any pressure unlike liquids and gases..

Answer 11

You must have seen that while solving questions we take their concentration as unity/one.

Answer 12

what about volume and temperature ?

Answer 13

u leave solid let us focus on liquid ?

Answer 14

Just like in an atom the core is the nucleus,same is the case for liquids and gases the root cause is the pressure,how tightly the molecules are packed,etc..everything falls to the same concept i.e particles are tightly packed,if they are tightly packed there will be less infact least pressure amongst them..so they are kind of non reactive I guess..
In liquids too,there is restricted movement amongst the molecules
Solids and liquids both do expand and contract (not detract) with temperature, but since there are various intermolecular forces at work in solids and liquids, then there is no single mathematical relationship to describe solids and liquids.

Answer 15

u mean the effect of P, T , V has larger difference is in case of gases and less differences in case of solids and liquids

Answer 16

hey thank you @Thee121 @DLS @Fifciol @JT950 for your valuable answers ,

Answer 17

kind of :)
