True or false? Three different types of states of matter are solids, liquids, and gases.
How do the particles move past each other in a solid?
They vibrate next to each other, forming neat rows.
They move past each other, but stay at a close distance and do not move fast.
Solids can't be compressed/squashed, and have a fixed volume.
Is heat energy the main form of energy, and is it stronger than cold energy?
Yes
No
Why does ice melt?
Ice is made up out of cold energy. As heat energy is stronger than cold energy, if the heat energy is applied to the ice, the particles start to move around each other again, and therefore start to flow, creating water.
Because the particles get sad
How do the particles move around each other when in water?
They are close and move at slowly around eachother
They are far away and move fast around each other
They are so close they vibrate against each and do not move
Can liquids be squashed? Do they have a fixed volume?
Yes, they can be squashed, as they have have a fixed volume.
Yes, they can be squashed, as they have a fixed volume.
No, they can't be squashed, as they have a fixed volume.
No, they can't be squashed, as they do not have a fixed volume.
What happens to water when it reaches boiling point?
First the water bubbles, then steams, becomes extremely hot and turns into a gas (therefore evaporating).
It stays the same, but gets really hot.
Can solids and liquids be measured?
What particles make up a molecule?
Hydrogen, hydrogen and oxygen
Hydrogen and oxygen
Hydrogen, hydrogen and hydrogen
It just is water
Do liquids have a fixed shape?
Yes - it has to as it can't be squashed.
No - They take on the shape of the container they are in.
How do the particles move around each other in their gas form?
They move quite fast around each other, and are spaced quite far apart.
They move slowly around each other, but at a far distance.
Can gases be squashed, and do they have a fixed volume?
Yes, as they do not have a fixed volume, and therefore can be compressed.
Yes, as they have a fixed volume.
No, as they have a fixed volume.
No, as they do not have a fixed volume.
Gases can be measured.
Yes, but with special instruments.
No, as they do not have a fixed volume, therefore it is impossible to measure it.
