Question

what is matter? Explain the properties of solids and liquids
​

Answer 1

Answer:

Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles. It will take the shape of its container.

Answer 2

Answer:

$\huge\underline\mathfrak\purple{Answer}$

Matter is anything that occupies space and has mass.

$\small\underline\mathfrak\pink{Properties:/of:/solid}$

• Particles are closely packed
• Interparticulate space is smallest as compared to other states of matter.
• Force of attraction is strongest.
• It has definite shape and volume.
• It is incompressible.(there are some exceptions such as sponge,ruberband etc.)
• They are rigid and cannot flow
• They have vibratory motion.
• It has very high density.
• It doesn't show diffusion.

$\huge\underline\mathfrak\pink{Extra:/ information-}$

Crystalline solids - They have regular geometric structure due to definite orderly arrangement of particles in their structure. They have high and sharp melting points. Ex- Diamond,NaCl (common salt).

Amorphous solids - These don't have fixed arrangement of their constitutional particles. They do not have sharp melting points and they are isotropic in nature.For example- Sulphur,rubber.

Isotropic- They have identical values of properties in a particular direction.

$\small\underline\mathfrak\purple{Properties:/ of:/ liquid}$

• They are less closely packed as compared to solids.
• The interparticulate space is larger than solids.
• The force of attraction is weaker than solid.
• It has definite volume but no definite shape.
• It is slightly compressible.
• It shows fluidity but it is lesser than that of gas
• The particles are free to move.
• It's density is lower than solids.
• It shows diffusion.
