States of Matter

Question 1

Properties of Solids

Answer 1

1. Fixed shapes
2. Fixed volume
3. Cannot be compressed

Question 2

Properties of Liquids

Answer 2

1. Takes the shape of any container
2. Can flow
3. Cannot be compressed
4. Fixed volume

Question 3

Properties of Gases

Answer 3

1. Takes the shape of any container
2. No fixed volume (it’s always changing)
3. Can flow
4. Compressible

Question 4

Particle theories of Solids

Answer 4

1. Particles are arranged in a fixed pattern
2. Particles stick together strongly and packed tightly
3. Particles don’t move, they vibrate in place

Question 5

Particle theories about Liquids

Answer 5

1. Particles can touch each other
2. Stick together weakly
3. The particles can slide passed one another

Question 6

Particle theories about Gases

Answer 6

1. Particles don’t touch
2. Particles are far apart
3. Particles spread out by themselves
4. Particles spread out and fill all spaces they are in

Question 7

What happens when u heat solid in terms of particles

Answer 7

Solids expands. When the solid is heated heat energy is transferred to particles and vibrate more and take up more space.

Question 8

What happens when u start melting solids

Answer 8

Particles vibrate more with more heat energy added and then the attractive forces between particles are broken.letting the particles to move freely.

Question 9

What happens when u start heating liquids

Answer 9

Particles move more as more heat energy is transferred and the weak attractive forces between the particles are broken allowing them to move freely and escape as gas

Question 10

What happens when gas cools

Answer 10

When gas particles lose heat,they move less and get closer together forming liquid.

Question 11

What happens when liquid freezes

Answer 11

When liquid particles lose heat, they cannot move and flow anymore. They can only vibrate in a fixed position.

Question 12

What processes are there in the water cycle

Answer 12

1) evaporation
2) transpiration
3) condensation
4)precipitation
5)percolation
6) surface run off

Question 13

What is transpiration?

Answer 13

Evaporation of water in plants

Question 14

What is precipitation?

Answer 14

When condensed water in cloulds become too heavy for air to hold them they fall back to earth as rain.
Examples: Rain, snow, hail and sleet

Question 15

What is surface run off?

Answer 15

A rain that reaches the surface of land that flow across the ground

Question 16

What is perculation?

Answer 16

Water which moves downwards through the soil.

Question 17

What are atoms?

Answer 17

They are tiny pieces of matter.

Question 18

What are elements?

Answer 18

A substance made of just ONE type of atom

Question 19

Elements can be divided into two type which are?

Answer 19

Metal and Non-metal

Question 20

What are compounds?

Answer 20

They are substances made of more than one type of atom.

Question 21

What are the properties of compounds?

Answer 21

1. Cannot be separated by physical methods.
2. They have completely new properties different from their individual elements

Question 22

What is the difference between compound and mixture?

Answer 22

Compound is chemically bonded and can only be separated through chemical methods while mixture can be separated by physical methods.
