Answer 1

Answer:Hey mate,

1. Matter is made up of very small particles.

2. volume is the space occupied by a matter..

3. ice is the solid state of matter.

4. A rubber band stretch when force is applied.

5. water is a universal solvent.

6. sand and water can be separated by decantation.

Matter and Its States

Matter typically exists in one of three states: solid , liquid , or gas . The state a given substance exhibits is also a physical property. Some substances exist as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. In addition to existing in one of the three states, matter can also undergo a change of state. A change of state occurs when matter is converted from one state to another state for example when a liquid is converted to a gas or a solid is converted to a liquid.

Note: Technically speaking a fourth state of matter called plasma exists, but it does not naturally occur on earth, so we will omit it from our study here.

Liquid

Liquids have the following characteristics:

no definite shape (takes the shape of its container)

has definite volume

particles are free to move over each other, but are still attracted to each other

A familiar liquid is mercury metal. Mercury is an anomaly. It is the only metal we know of that is liquid at room temperature. Mercury also has an ability to stick to itself (surface tension) – a property all liquids exhibit. Mercury has a relatively high surface tension, which makes it very unique. Here you see mercury in its common liquid form.

Mercury is a liquid at room temperature

Mercury.

If we were to heat liquid mercury to its boiling point of 357°C, and under the right pressure conditions, we would notice all particles in the liquid state go into the gas state.

Gas

Gases have the following characteristics:

no definite shape (takes the shape of its container)

no definite volume

particles move in random motion with little or no attraction to each other

highly compressible

Solid

Solids are defined by the following characteristics:

definite shape (rigid)

definite volume

particles vibrate around fixed axes

If we were to cool liquid mercury to its freezing point of -39°C, and under the right pressure conditions, we would notice all of the liquid particles would go into the solid state.

hope will help!!

Do well

Answer 2

Fill in the blanks :-

1. Matter is made up of very small atoms .
2. Volume is the space occupied by a matter.
3. Ice is the solid state of matter.
4. A rubber band expands when force is applied.
5. Water is a universal solvent.
6. Sand and water can be separated by decantation .

More to know :-

Solid :- A substance having least intermolecular space and most intermolecular force . It is

hard and has infinite number of free surface.

Liquid :- A substance having more intermolecular space as compared to solid and less intermolecular force as compared to solid. It can flow and has only 1 free surface.

Gas :- A substance having most intermolecular space and least intermolecular force. It can also flow and has no free surface.
