Question

A. tabulate the differences in the characteristices of the three states of matter.

Answer 1

Answer:

 

 $\boxed{\boxed{\bf SOLIDS :}}$

1. Particles are closely packed.
2. Attraction forces are highest.
3. They possess definite shape, mass and volume.
4. The particles are fixed and possess the least energy.
5. They have least compressibility.
6. They possess the highest density.

$\boxed{\boxed{\bf LIQUIDS :}}$

1. Particles are loosely packed.
2. Attraction forces are less than of solids.
3. They do not possess definite shape but possess definite mass and volume.
4. Particles are free to move and have higher energies than that of solids.
5. They have higher compressibility Than solids.
6. They possess lower density than of solids.

$\boxed{\boxed{\bf GASES :}}$

1. Particles are at a sufficient distance apart.
2. Attraction forces are minimum.
3. They possess neither definite shape, nor definite volume but possess definite mass.
4. The particles have maximum freedom of motion and possess maximum energies.
5. They have the highest compressibility.
6. They possess least density.

Answer 2

Answer:

What is matter?

Matter is a substance which occupies pysical space.

States of matter:

1.Solid.

2.Liquid.

3.Gas.

$\large{\underline{\boxed{\tt Solid}}}$

• Particles are tightly packed with each other.
• Solid has fixed volume and space.
• Solid has slow diffusion and low vapour.
• A solid is rigid and cannot be compressed easily.

$\large{\underline{\boxed{\tt Liquid}}}$

• Liquids have definite volume, but indefinite shape.
• When a liquid is inside a container, it will take its shape.
• Particles are free to move over each other, but are still attracted to each other.
• They possess lower density than of solids.

$\large{\underline{\boxed{\tt Gases}}}$

• Particles of gases are move freely around.
• It can compress easily.
• Particles move in random motion with little or no attraction to each other.
• It has no defined volume.
