Question

1. What is matter ? Name the three states of matter.
2. Which main factors influence the physical state of matter?
3. Arrange the three states of matter in the order of spacing between particles.
4. When sugar is dissolved in water, there is no increase in volume. Why? 5. A incense stick is lighted in a corner of a room spreads fragrance in the whole room. Why?​

Answer 1

1) There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

2) Answer:Temperature ,pressure and intermolecular space.

3) Particles in a:

• gas are well separated with no regular arrangement.
• liquid are close together with no regular arrangement.
• solid are tightly packed, usually in a regular pattern.

4) yes, there is no increase in volume because the space present between the atoms of water is occupied by the sugar. therefore ifsugar is dissolved in water there is no increase in volume.

5) Complete answer:

The fragrance of burning incense sticks spreads all around due to the diffusion of its smoke into the air. Also, it spreads because the particles move continuously in all the directions. Its fragrance spreads quickly in the entire room because on heating the kinetic energy increases.

Answer 2

Answer:

1. matter is anything occupy space and has mass is called matter.

for ex : chair, wood, etc.

here are three state of matter

1. solid

2. liquid

3. gas

2. temperature, pressure, inter molecular spaces.

3. we know that three physical state of matter :-

in solid have very tiny space in each particle.

In liquid have some spaces to each particle

In gas have very large spaces to each particle.

4. sugar that particle are very small to comparison to water sugar go in water and water is liquid that means some space. in that sugar particle mix water particle so this is reason for why sugar mix water not increase volume.

5. when incense stick burning we get some gases that spreading and mix with air particle then diffusion. so therefore diffusion is called the cause of burning incense stick to spread room.
