States of Matter

Question 1

What are the three states of matter/

Answer 1

liquids, solids and gases

Question 2

What are solids?

Answer 2

materials with a definite shape and volume

they cannot be compressed because the particules are very close in a regular arrangement

Question 3

Why are the particles in a solid close?

Answer 3

Because they have a a strong attraction for each other called Intermolecular Forces (IMF)

Question 4

What are liquids?

Answer 4

materials with the ability to take the shape of the container but have a fixed volume
particles are slightly further apart but still cannot be compressed

Question 5

What is translational motion?

Answer 5

particles vibrate but can also slide past each other (liquids)

Question 6

What are gases?

Answer 6

materials that take the shape and volume of the containers
particles are far apart and very compressible
in constant random motion

Question 7

Each matter with their type of energy

Answer 7

Solids - vibrational
Liquids - vibrational, translational
Gases - vibrational, translational, rotational

Question 8

What is it called when one state of a matter changes into another?

Answer 8

phase changes

Question 9

Are phase changes physical or chemical changes?

Answer 9

physical changes bc material stays chemically the same

Question 10

Solid ➡ Liquid

Answer 10

Melting

Question 11

Answer 11

Vaporization/ Boiling

Question 12

Gas ➡ Solid

Answer 12

Deposition

Question 13

Solid ➡ Gas

Answer 13

Sublimation

Question 14

Gas ➡ Liquid

Answer 14

Condensation

Question 15

Liquid ➡Solid

Answer 15

Freezing/ Fusion

Question 16

How do we measur ethe average kinetic energy of particles in a substance?

Answer 16

Through temperature

Question 17

What is the kinetic energy of particles?

Answer 17

The energy the particles have due to their motion

Question 18

As we go Solid ➡ Liquid ➡ Gas what increases?

Answer 18

Interparticle Distance
Potential Energy
Kinetic Energy
Temperature

Question 19

What is another way to change the state of matter?

Answer 19

add or remove pressure

Question 20

If a substance fills the container it is in completely and takes the shape of the container, what state of matter is the substance?

Answer 20

Gas

Question 21

What is the name of the phase change from a gas to solid?

Answer 21

Deposition

Question 22

If the substance has its own volume but takes the shape of the container, what state of matter is it?

Answer 22

Liquid

Question 23

What type of matter only has vibrational kinetic energy?

Answer 23

Solid
