Question

Which is not true about the solid
state?
(a) they have definite shape and
volume
(b) they have high attractive
forces among molecules
10) they have high vapour
pressure
(d) they have high density and
low compressibility
​

Answer 1

c.they have high vapor pressure

it is false about solid state

hope it helps you

Answer 2

"Solids have high vapor pressure" is the wrong statement (option-c).

• Matter can be divided into the following 3 types, on the basis of its state.

1. Gas
2. Liquid
3. Solid

• Various characteristics of solid-state are as follows:-

1. Fixed shape and size
2. Definite volume
3. Closely packed particles
4. High density

• They are able to maintain a particular shape and size as the force of attraction between their constituent particles is very high.
• Solids are not easily compressed due to a lack of space between their particles as they are very tightly packed.
• Vapour pressure is defined as the pressure applied by the vapor form on its solid or liquid state at equilibrium.
• It is a property that depends on the strength of intermolecular forces and solids have the highest attraction forces, therefore difficult to convert in the vapor state. Hence, solids have a low vapor pressure.
