Question One:

List the three states of matter and describe the speed and attraction of the particles in each state.

- Solid - A solid's particles tend to have a much slower vibration than those of a liquid or a gas which cannot pass the intense attraction that they have towards each other.

- Liquid - A liquid's particles vibrate slightly faster than those of a solid but can only break free of their attraction long enough to move slightly, only slightly, away from each other.

- Gas - A gas's particles, however, have the ability to move fast enough to break the attraction from one another and are able to move around freely.

Question Two:

Which state has definite shape and volume?

Solid is the state of matter that has definite shape and volume. The particles are packed together and do not give enough room for the object to lose its shape or volume.

Question Three:

What are the two kinds of solids and how are the particles arranged in each?

There are two types of solids; crystalline and amorphous. Crystalline solids tend to be the most common type of solid and these solids usually have their particles arranged in a three-dimensional style. Amorphous is the least common kind of solid out of the two but, surprisingly for a solid, does not have a certain arrangement of particle.

Question Four:

Which state changes shape but has a definite volume?

Liquid is the state of matter that can change shape but also has a definite volume. The particles in a liquid are compact enough to form something with volume but are not as compact as those in solids. Therefore they are free to move, spreading out slightly.

Question Five:

What are the two characteristics of liquid? Identify and define each.

There are two different characteristics of the liquid state of matter. One of the characteristics is that liquids can change their shape. The particles are loosely held together and are able to slide past one another, thus changing it's shape. The other characteristic is that liquids always have definite volume, which gives it a three-dimensional quality - height, width and length.

Question Six:

Which state does not have definite shape or volume?

Gas is the state of matter which does not have a definite shape or volume. The spread-apart particles are free to move around as they please and the volume usually takes the shape of the container it is in.

Question Seven:

Define change of state.

A change of state is where a solid turns into a liquid (melting), a liquid turns into a gas (evaporation), a gas turns into a liquid (condensation), a liquid turns into a solid (freezing) or a solid turns into a gas (sublimation). Basically it is where one state of matter (either solid, liquid or gas) turns into another state of matter - usually as a result of increase or decrease in temperature.

Question Eight:

Are changes of state physical or chemical changes?

The changes of state are considered to be physical changes as, unlike chemical changes, a new substance is not actually formed. Instead the same substance is just being liquified/evaporated/solidified.
