100
What are the 3 states of matter in order from the LEAST to MOST amount of energy of the particles?
SOLID, LIQUID, GAS
100
The term for when a liquid turns into a gas?
Evaporation.
100
What does the Particle Model of Matter state about what happens when heat is added to matter?
Adding heat makes the particles move faster.
100
How do the molecules of ice MOVE and how are they ARRANGED?
They move in a fixed position.
They are in a formation called a crystal lattice.
100
Name the following states of matter in order
Gas, Solid, Liquid
200
Liquids have a fixed shape, but not a fixed volume. True or False?
False. Liquids have no fixed shape, but have a fixed volume.
200
What is the term called for when a gas turns into a liquid?
Condensation.
200
What happens to the spaces between the particles when a solid is heated and why?
The spaces between the particles in the sold increases because they are vibrating faster and so need more room to move.
200
How do water molecules behave ?
They move past each other.
200
All matter is made up of
Atoms
300
Name two properties of a solid.
Example: has a fixed shape, they have a fixed volume , cannot be compressed.
300
What is the opposite of evaporation?
Condensation.
300
Give 2 examples of what happens to the particles in a liquid during contraction (when heat is taken away).
The lose KE, particles move closer together
300
How do water vapour molecules behave?
They move around radomnly.
300
Matter can exist in different states, depending on its
Temperature
400
Which states of matter take the shape of their container?
Liquids and gas.
400
What do you call when a liquid becomes a solid?
Freezing.
400
When a liquid is heated what happens to the volume of the liquid?
The volume increases
400
What happens to ice molecules if we add energy to them?
They split and start moving. The ice turns into water.
400
Can matter be created or destroyed?
NO!
500
Which states of matter cannot be compressed?
Solids and Liquids.
500
Name the changes of state from 1-6 in the diagram
1. evaporation
2. melting
3. Deposition
4. condensation
5. freezing
6. sublimation
500
When we add heat, what are we adding to the molecules?
Energy.
500
What happens to water vapour molecules when we remove energy?
They move slower. The water vapour becomes water.
500
Compared with the Pacific Ocean, a cup of hot chocolate has more or less thermal energy
Which has more thermal energy the Pacific Ocean or a cup of hot chocolate?
Water in the Pacific Ocean has more thermal energy This is because Pacific Ocean contains more molecules which means it has more kinetic energy which creates more thermal energy.
600
Which state/s of matter do not have a fixed VOLUME?
Gases
600
What is happened in the graph when the temperature plateau's (stops rising) between points B and C and points D and E?
The plateau's represent the changes in state
600
In this heating curve of ice, what state/s is the water in during:
stage B and C and stage D and E
B and C -a mixture of solid ice and water
D and E - water and steam (gas)
600
How do particles in a solid move and why?
They vibrate because they only have a small amount of Kinetic Energy.
600
what is the definition of matter
Anything that has MASS and takes up SPACE
