Hope it helps

Thank you

Explanation:

Answer1.) The difference in the characteristics of three states of matter-

(i) Shape-

a.)Solid has fixed form

b.) liquid has no fixed shape

c.)gas has no fixed shape.

          

(ii) Volume-

a.) Solid has fixed volume

b.) the fluid has fixed volume

c.) gas has no fixed volume.

(iii) Rigidity/fluidity-

a.) Solids are rigid and cannot flow

b.) fluid can flow and have no any rigidity

c.) gas can flow and have no rigidity.

(iv) Intermolecular force and space-

a.) Solids have a high intermolecular force and less space

b.) liquid has an intermediate intermolecular force and has space more than solids

c.)Gas has a very less intermolecular force and has high space

Answer2.) HOMOGENEOUS MIXTURE:-

• A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.
• Particle size distinguishes homogeneous solutions from other heterogeneous mixtures. Solutions have particles which are the size of atoms or molecules - too small to be seen.

• A colloid is a homogeneous solution with intermediate particle size between a solution and a suspension. Colloid particles may be seen in a beam of light such as dust in air in a "shaft" of sunlight. Milk, fog, and jello are examples of colloids.
• In contrast a suspension is a heterogeneous mixture of larger particles. These particles are visible and will settle out on standing. Examples of suspensions are: fine sand or silt in water or tomato juice.
• Corn oil is homogeneous, White vinegar is homogeneous. A sugar solution is homogeneous since only a colorless liquid is observed. Air with no clouds is homogeneous

HETEROGENEOUS MIXTURE:-

• A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
• In  contrast a suspension is a heterogeneous mixture of larger particles. These particles are visible and will settle out on standing. Examples of suspensions are: fine sand or silt in water or tomato juice.

For example beach sand is heterogeneous since you can see different colored particles. Vinegar and oil salad dressing is heterogeneous since two liquid layers are present, as well as solids. Air with clouds is heterogeneous, as the clouds contain tiny droplets of liquid water.

Answer3.) name the following:-

1. Squamous epithilial
2. Tendons
3. Adipose tissue
4. Phloem
5. Blood
6. Nervous tissue

Answer 2

HERE ARE YOUR ANSWERS DEAR ARMY

THE ABOVE ATTACHMENT SHOWS THE DIFFERENCE BETWEEN THE PROPERTIES OF SOLID, LIQUID AND GAS....

1. 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. Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.

2. A mixture is which the components are mixed uniformly in a way thay they cannot be seen separately is called homogeneous mixtures. Eg. Salt dissolved in water,sugar syrup, tap water.

A mixture in which the components are not mixed uniformly and can be seen separately is called a heterogeneous mixture.Eg. Iron filling and sulphur powder, chalk and water, oil and water.

3.

a) Squamous Epithelium

b) Dense connective tissue ; Tendons

c) Loose connective tissue ; Adipose tissue

d) Complex tissue ; Phloem

e) Blood

f) Nervous tissue
