What does state of matter depend on?
the forces between particles
1 of 34
forces in solids have...
strong attractions between the particles
2 of 34
forces in liquids have...
some force of attraction between particles
3 of 34
forces in gases have...
no force of attraction between particles
4 of 34
soilids hold a definite what
shape and volume
5 of 34
why does a solid expand slightly when heated
because the particles in the solid vibrate more
6 of 34
liquids keep the same ................ but change....................
volume shape
7 of 34
What do the particles in a liquid do
constantly move in a random motion
8 of 34
What happens to a liquids particles as it heats up
the particles move faster
9 of 34
do particles in a gas move in a curved line or straight line
straight line
10 of 34
why might the path of a gas particle change
it collides with another particle
11 of 34
what shape and volume do a gas have
none, they move freely
12 of 34
What 2 things happen to gases when they heat up
expand and pressure increases
13 of 34
name the process that takes place so we can smell stuff
volatility
14 of 34
explain the process of volatility
the particles evaporate from the liquid. As they have overcome the attraction to each other and evaporated.
15 of 34
Name something that is volatile
perfume
16 of 34
What is a solution
a mixture of a solvent and solute
17 of 34
What is a solute
substance being dissolved
18 of 34
What is a solvent
liquid its dissolving into
19 of 34
What is soluble
something that will dissolve
20 of 34
What is insoluble
something that will not dissolve
21 of 34
What is solubility
a measure of how much will dissolve
22 of 34
whys nail varnish insoluble in water
because the 2 substances are more attracted to themselves than each other, so they dont form a solution
23 of 34
whys nail varnish soluble in acetone
attraction in acetone and nail varnish molecules are stronger than the attractions holding the 2 substances together
24 of 34
what does a pigment do
gives paint its colour
25 of 34
a paint is a ..............
colloid
26 of 34
what does a colloid consist of
really tiny particles of stuff dispersed in another kind of stuff
27 of 34
whys paint a colloid
particles of a pigment are dispersed through a liquid
28 of 34
how does water based paint dry
paint dries as solvent evaporates
29 of 34
what are the two types of paints
water based and oil based
30 of 34
how does an oil based paint dry
solvent evaporates and oil is oxidized by the oxygen in the air before turning solid
31 of 34
whats a therochromic pigment
changes colour when heated
32 of 34
what is a phosphorescent pigment
glows in the dark
33 of 34
what pigment would be used in baby spoons
thermochromic
