KS2 Matter Quiz: Explore States of Solids, Liquids, Gases

Science Quiz - Solids, Liquids and Gases 02 (Questions)

Let's dive into the world of matter with this second KS2 Science quiz! It's all about solids, liquids, and gases - from how particles behave to what gases make up the air.

In science, we learn about three types of matter: solid, liquid, and gas. They each act differently - you can't cut a gas or pour a solid! Matter can change its state, like gas turning into liquid. This happens because particles in gases have more energy. Heating them up makes particles move, turning ice to water and water to steam.

Test your knowledge with this cool KS2 Science quiz on the amazing states of matter!

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

[ ]	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 Quiz - Solids, Liquids and Gases 02 (Answers)

What is solid water called?

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

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 vapour

Water vapour is also called steam. Steam is invisible - what you see rising from a kettle or a pan are 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 sweets 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 gases

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 gases, 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

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)
