Question 1

What is the kinetic particle theory ?

Answer 1

It explains the properties of different states of matter

Question 2

What are the three states of matter ?

Answer 2

Solid,liquid,has

Question 3

How are particles in a solid arranged ?

Answer 3

Very tightly packed together in ordered rows

Question 4

How are particles in a liquid arranged ?

Answer 4

Tightly packed together but with small gaps to allow small amount of movement, no order to the particles

Question 5

How are gases arranged ?

Answer 5

Very spread out with no structure or order to the particles

Question 6

How do particles move in a solid ?

Answer 6

They can vibrate and as they are tightly packed together the vibrations are carried throughout the whole thing

Question 7

How do particles in a liquid move ?

Answer 7

They can move around each other in the small gaps however they are all constantly touching each other

Question 8

How do particles in a gas move ?

Answer 8

They move randomly and quickly in all directions around each other bouncing of objects

Question 9

What properties do solids have an why ?

Answer 9

Solids have a fixed shape and therefore can’t flow, this is because they are very tightly bonded
Solids cannot be compressed or squashed as they are so tightly packed that there is no space to move into

Question 10

What properties do liquids have and why ?

Answer 10

Liquids can flow and take the shape of their container, this happens as there particles can move around each other
Liquids can not be compressed or squashed as they are very tightly packed together

Question 11

What properties do gases have and why ?

Answer 11

Gases flow and completely fill there container because there particles can move in all directions
Gases can be compressed as there particles are far apart and have lots of space to move into

Question 12

What is the process when solid goes to liquid ?

Answer 12

Melting

Question 13

What is the process when liquid changes to gases ?

Answer 13

Evaporation

Question 14

What is the process when gas changes to liquid ?

Answer 14

Condensation

Question 15

What is the process when liquid changes to solid ?

Answer 15

Freezing

Question 16

Why does melting and evaporating need heat ?

Answer 16

As a solid has less energy than liquid, and liquid has less energy than a gas it needs more beefy to turn into a state with more energy

Question 17

When can solids turn straight into a gas ?

Answer 17

When solids turn into gases it’s called sublimation fit example dry ice which is co2

Question 18

How can a gas turn into a liquid without using condensation ?

Answer 18

When gas is kept at a very high pressure this is because the particles are compacted so much that bonds are made between them
