States of matter

Question 1

describe the state of a liquid?

Answer 1

particles are close together but not regularly arranged

particles have a little more kinetic energy than in a solid

there are fewer electrostatic forces between particles than in a solid - allowing particles to move past each other and flow

Question 2

what does the kinetic theory?

Answer 2

it explains the differences in physical properties of solids, liquids and gases by referring to the arrangement and motion of particles

Question 3

solid to liquid

Answer 3

melting

Question 4

liquid to solid

Answer 4

freezing

Question 4

liquid to gas

Answer 4

evaporation

Question 5

gas to liquid

Answer 5

condensing

Question 6

solid to gas

Answer 6

sublimation

Question 7

SOLIDS

Answer 7

solids have strong forces of attractions between each other, which holds them close together to form a very regular lattice arrangement.

the particles don’t move from their positions, so all solids keep a definite shape and volume, but don’t flow like liquids.

particles vibrate- the hotter the solid becomes, the more they vibrate.

Question 8

LIQUIDS

Answer 8

liquids is a weak force between the particles. they’e randomly arranged and free to move, but tend to stick closely together.

they have a definite volume but don’t keep a definite shape, and will flow to fill the bottom of a container

particles are constantly moving with random motion. the hotter the liquid gets, the faster they move.

Question 9

Melting point of ice/water

Answer 9

0 C
Ice melts into water
Water freezes/solidifies into ice

Question 9

GASES

Answer 9

gases, the force of attraction is very weak- they’re free to move and far apart. particles travel in straight lines.

hey don’t keep a definite shape or volume and will always fill any container

particles move constantly with random motion. the hotter the gas gets, the faster they move.

Question 10

Boiling point of water

Answer 10

100 C
water boils/evaporates into steam
steam condenses into water
