What is everything made up of?

• Atoms

• Elements

• Molecules

• Compounds

Answer explanation

Even we are made up of atoms everything is made up of atoms there is no doubt, elements are made up of atoms.

What are the 3/4 main types of state of matter?

• Solids, liquids, gases and plasma

• Solids, liquids and gases and particles

• Solids, liquids and gases

Answer explanation

In ks3 we do not learn about plasma but don’t worry if you got this question wrong.

What would would the particles look like in a solid object?

• 
• 
• 
• 

Answer explanation

In a solid, the particles only vibrate inside they don't move anywhere and covers all of the space.

What does the particles look like in a liquid?

• 
• 
• 
• Neither it has no particles

Answer explanation

A liquids particles is still different compared how solids particles move. They can move quite close together with random motion.

What does particles look like in a gas?

• 
• 
• Both

• Neither they are not living things.

Answer explanation

Gas particles are widely separated from one and another. They do not have a fixed shape or volume. Gases can also be compressed.

What does particles look like in plasma?

• 
• 
• Both

• Neither of them whatsoever

Answer explanation

Plasma is often called 'the fourth state of matter'. When heating a gas it will form a plasma- a soup of negatively charged particles (electrons) and positively charged particles (ions).

What are ions?

• ion, any atom or group of atoms that bears one or more positive or negative electrical charges

• Another word for electrons

• Another word for subatomic particles

• Another word for protons

• Another word for neutrons

Answer explanation

Positively charged ions are called cations; negatively charged ions, anions. A molecular cluster of about 10 molecules bound by polarizing forces to a single charged oxygen or nitrogen molecule.

You cannot compress a solid, but sponges is a solid so how can you compress a sponge?

• A sponge can be compressed easily but still we count them in solids because they have minute pores in it which are filled with air

• Because a sponge is a sponge and I don't know

• A sponge can be compressed because of its material

• Sponges are soft so you can was dishes

Answer explanation

When we press the sponge air is expelled from its holes making it highly compressible. Because of air.

What are subatomic particles?

• Protons, neutrons and electrons

• Atoms which bounce into other atoms

• Particles which are around us

• Compounds, molecules and elements

Answer explanation

Subatomic particles is a word for electrons, neutrons and protons they are all in a atom.

What is condensation?

• A reaction from gas to liquid

• A reaction from liquid to gas

• A reaction from solid to liquid

• A reaction from liquid to solid

Answer explanation

Condensation is the change from gas particles turns into a liquid. Don't worry and try your best!
