The three states of matter are solid, liquid and gas. Each of these behaves in a different way. For example, it is not possible to cut a gas or to pour a solid. Matter can change state, moving from gas to liquid or liquid to solid - and vise versa. This is because the particles in gasses have more energy than those in liquids and so can move aroud much more. The particles in liquids have less energy than those in gasses but more than those in gasses and so move less than in gasses but more than in solids. The particles in solids barely move at all. We can give energy to the particles by heating them up. That's how ice melts into water and water evaporates into steam.

What is solid water called?

[ ]	Magma
[ ]	Dry ice
[ ]	Ice
[ ]	Water vapor

What is water called when it is a gas?

[ ]	Helium
[ ]	Carbon dioxide
[ ]	Nitrogen
[ ]	Water vapor

Can sugar become a liquid?

[ ]	Yes, when it is heated to a very high temperature
[ ]	Yes, when it is heated to 100° Celsius
[ ]	Sometimes, depending on what type of sugar it is
[ ]	Sugar can never become liquid

When a material is heated, what happens to its particles?

[ ]	They lose energy and become more strongly attached (attracted) to other particles
[ ]	They gain energy and become less strongly attached (attracted) to other particles
[ ]	They begin to stick together
[ ]	They stop moving

Which of the following describes what happens when water evaporates?

[ ]	Gravity causes the water to run downhill and disappear
[ ]	The water gradually becomes solid and these solids break away from the liquid
[ ]	The water doesn't exist any longer
[ ]	Particles gain enough energy to break free from the liquid's surface

In cooler temperatures, how do the particles of any material move?

[ ]	More slowly
[ ]	More quickly
[ ]	Alternately slowly and quickly
[ ]	Particles never change how they move

In warmer temperatures, how do particles of any material move?

[ ]	More slowly
[ ]	More quickly
[ ]	Alternately slowly and quickly
[ ]	Particles never change how they move

Although air is made up of several gasses, the two main ones are nitrogen and which other?

[ ]	Helium
[ ]	Oxygen
[ ]	Carbon dioxide
[ ]	Methane

In order to smell, particles from the object must enter your nose. In which state of matter are these particles?

[ ]	Solid
[ ]	Liquid
[ ]	Gas
[ ]	Liquid or gas

Science: Middle School: Grades 6, 7 and 8 Quiz - Solids, Liquids and Gases 2 (Answers)

What is solid water called?

[ ]	Magma
[ ]	Dry ice
[x]	Ice
[ ]	Water vapor

When water is placed in the freezer, it becomes a solid - ice

What is water called when it is a gas?

[ ]	Helium
[ ]	Carbon dioxide
[ ]	Nitrogen
[x]	Water vapor

Water vapor is also called steam. Steam is invisible - what you see rising from a kettle or a pan is water droplets in the air

Can sugar become a liquid?

[x]	Yes, when it is heated to a very high temperature
[ ]	Yes, when it is heated to 100° Celsius
[ ]	Sometimes, depending on what type of sugar it is
[ ]	Sugar can never become liquid

Sugar becomes liquid at around 186° C - heating sugars to such high temperatures is how candies are made

When a material is heated, what happens to its particles?

[ ]	They lose energy and become more strongly attached (attracted) to other particles
[x]	They gain energy and become less strongly attached (attracted) to other particles
[ ]	They begin to stick together
[ ]	They stop moving

Heat gives energy to the particles and makes them vibrate or move

Which of the following describes what happens when water evaporates?

[ ]	Gravity causes the water to run downhill and disappear
[ ]	The water gradually becomes solid and these solids break away from the liquid
[ ]	The water doesn't exist any longer
[x]	Particles gain enough energy to break free from the liquid's surface

If a particle gets enough energy it leaves the liquid. Particles like this form gasses

In cooler temperatures, how do the particles of any material move?

[x]	More slowly
[ ]	More quickly
[ ]	Alternately slowly and quickly
[ ]	Particles never change how they move

Cooler particles have less energy

In warmer temperatures, how do particles of any material move?

[ ]	More slowly
[x]	More quickly
[ ]	Alternately slowly and quickly
[ ]	Particles never change how they move

Warmer particles have more energy

Although air is made up of several gasses, the two main ones are nitrogen and which other?

[ ]	Helium
[x]	Oxygen
[ ]	Carbon dioxide
[ ]	Methane

Animals - including people - need oxygen to breathe!

In order to smell, particles from the object must enter your nose. In which state of matter are these particles?

[ ]	Solid
[ ]	Liquid
[x]	Gas
[ ]	Liquid or gas

You breathe the gas in through your nose and detect any smell which pass through

10.

A sweet fizzy drink contains what?

[ ]	Solid only
[ ]	Liquid only
[ ]	Gas only
[x]	Solid, liquid and gas

Sweetened fizzy drinks contain solid (sugar), liquid (water) and gas (carbon dioxide)
