Q

what is compound

A

pure substance. chemical combination of two or more elements. elements making up the compound are combined in fixed ratios. can only be separated by chemical means. properties of the compound are different from the properties of its elements

Q

solid

A

strong forces hold the particles in a pattern called the crystal lattice
particles vibrate in a fixed position
has its own shape
has its own volume
particles are close together, not compressible

Q

liquid

A

forces still hold particles together but they are weaker than the forces of a solid
particles are able to change places, they can move over each other and thus the liquid can be poured
takes on the shape of the container
has its own volume
particles are close together, not compressible

Q

gas

A

forces between particles are almost non-existent
particles are free to move and thus fill the whole container
has no shape, fills container
fills container, has volume of container
particles are far apart, compressible

16
Q

what is a neutron

A

combines with the potons, it makes up the nucleus of the atom, which is the mass (mass number)

17
Q

what charge does a neutron have

A

no charge

18
Q

what is a proton

A

it is the mass and the charge of the atom (atomic number )and is combined with the neutrons in the nucleus to make up the mass number

19
Q

what is a homogeneous mixture

A

solution- take on one of the substances properties

eg . salt water

20
Q

what is a heterogeneous mixture

A

substances retain their individual properties.

eg. sand and water

21
Q

what are two types of compounds

A 
molecule (non-metal + non-metal)
crystal lattice (metal + non-metal)
22
Q

what are the diatomic elements

A 
hydrogen
nitrogen
flourine
clorine
bromine
iodine
23
Q

A 
ionic bond (metal+non-metal)
covalent bond (non-metal+non-metal)
metallic bond (metal+metal)
24

A

going straight from a solid to a gas

29
Q

what is deposition

A

going straight from a gas to a solid

30
Q

what is diffusion

A

the process whereby liquid or gas particles move from an area of high concentration to an area of low concentration

31
Q

what is density

A

the degree of compactness of the particle of a substance. (the amount of mass of matter is contained in a given volume of the substance)

32
Q

what is expansion

A

the increase in the size of spaces between particles of a substance

33
Q

contraction

A

the decrease in the size of the space between the particles of a substance

34
Q

when particles are changing phase what kind of energy do they have

A

the have kinetic and potential energy

35
Q

what happens when a solid substance is heating to its melting point

A

further heat transfer to the molecules increases their potential energy

36
Q

what happens to the heat added to a liquid when boiling

A

it gets converted into potential energy
