Pregunta 2
Pregunta
True or false? Three different types of states of matter are solids, liquids, and gases.
Respuesta
- True
- False
Pregunta 3
Pregunta
How do the particles move past each other in a solid?
Respuesta
-
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.
Pregunta 4
Pregunta
Solids can't be compressed/squashed, and have a fixed volume.
Respuesta
- True
- False
Pregunta 5
Pregunta
Is heat energy the main form of energy, and is it stronger than cold energy?
Respuesta
-
Yes
-
No
Pregunta 6
Pregunta
Why does ice melt?
Respuesta
-
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
Pregunta 7
Pregunta
How do the particles move around each other when in water?
Respuesta
-
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
Pregunta 8
Pregunta
Can liquids be squashed? Do they have a fixed volume?
Respuesta
-
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.
Pregunta 9
Pregunta
What happens to water when it reaches boiling point?
Respuesta
-
First the water bubbles, then steams, becomes extremely hot and turns into a gas (therefore evaporating).
-
It stays the same, but gets really hot.
Pregunta 10
Pregunta
Can solids and liquids be measured?
Respuesta
-
Yes
-
No
Pregunta 11
Pregunta
What particles make up a molecule?
Respuesta
-
Hydrogen, hydrogen and oxygen
-
Hydrogen and oxygen
-
Hydrogen, hydrogen and hydrogen
-
It just is water
Pregunta 12
Pregunta
Do liquids have a fixed shape?
Respuesta
-
Yes - it has to as it can't be squashed.
-
No - They take on the shape of the container they are in.
Pregunta 13
Pregunta
How do the particles move around each other in their gas form?
Respuesta
-
They move quite fast around each other, and are spaced quite far apart.
-
They move slowly around each other, but at a far distance.
Pregunta 14
Pregunta
Can gases be squashed, and do they have a fixed volume?
Respuesta
-
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.
Pregunta 15
Pregunta
Gases can be measured.
Respuesta
-
Yes, but with special instruments.
-
No, as they do not have a fixed volume, therefore it is impossible to measure it.
