States of Matter

Question 1

Define Solid

Answer 1

A solid is a state matter that has a fixed shape and volume. Atoms are boud together

Question 2

Define liquid

Answer 2

A liquid is a state of matter that has a fixed volume but not a fixed shape, it takes on eh shape of its container. Atmos are loosely bounded together

Question 3

Define gas

Answer 3

Does not have a fixed shape or volume. Atoms move freely wherever they want

Question 4

Define Volume

Answer 4

volume is the measurement of how much space is taken up by a substance or object

Question 5

Define fluid

Answer 5

Fluid is any substance or material that will flow in response to an applied force

Question 6

Define mass

Answer 6

Mass is the measurement of how much quanitiy of matter an object/substance has

Question 7

Define particle model

Answer 7

A particle model is a model that descirbes how particles move around and behave in an object/substance. The model explains the properties of solids, liquids and gases.

Question 8

Define Melting

Answer 8

Melting is where a solid is transformed into a liquid from applied heat

Question 9

Define Melting point

Answer 9

Melting point is the temperature at which a solid begins to melt into a lquid

Question 10

Define boiling

Answer 10

Boiling occurs when a substance is getting heated. Bubbles will occur and eb=ventually this will result in avaporation

Question 11

Define evaporation

Answer 11

Evaporation is where a liquid transforms into a gas from applied heat and evaporates into the air

Question 12

Define boiling point

Answer 12

the temperature at which a liquid changes to a gas

Question 13

define freezing

Answer 13

freezing is when a liquid object/substance gets heat taken away from it and turns into a solid

Question 14

define freezing point

Answer 14

freezing point is the temperature in which a liquid starts to solidify

Question 15

define sublimation

Answer 15

the change in state from a solid into a gas without first becoming a liquid

Question 16

Define property

Answer 16

characteristics or features of an object or substance

Question 17

define expand

Answer 17

increase in size due to the movement of particles in a substance/object

Question 18

define contract

Answer 18

decrease/shorten in size due to less movement of particles in a substance

Question 19

How properties of a liquid is related to the behaviour of the particles

Answer 19

Liquid particles roll over each other. But they cannot ‘escape’. For this reason, they have a fixed volume, but the rolling motion allows them to take up the shape of its container

Question 20

How properties of a solid is related to the behaviour of the particles

Answer 20

Solid particles are tightly bound together so they cannot be compressed. Bonds between particles are very strong and particles are not able to move around, exaplaining their fixed shape.

Question 21

How properties of a gas is related to the behaviour of the particles

Answer 21

Gas particles’ attraction are so weak, they can move around freely in any direction. Gases spread out and take up any space. Gasses can be compressed because of the weak attraction of particles.

Question 22

draw a moel describing the particles for different states of matter

Question 23

The hotter particles are…

Answer 23

the faster the aprticle smove

Question 24

liquid to solid

Answer 24

solidify (freeze)

Question 25

solid to liquid

Answer 25

liquify (melt)

Question 26

gas to liquid

Answer 26

condensation

Question 27

liquid to gas

Answer 27

evaporation

Question 28

solid to gas

Answer 28

sublimation

Question 29

gas to solid

Answer 29

deposition
