## Resource summary

### Question 1

Question
What does the kinetic theory of matter state?
• All matter is made up of very small cells that are in constant motion
• For every action there is an equal and opposite reaction
• The particles of a substance will stay at rest unless heated
• All matter is made of small particles that are in continuous random motion

### Question 2

Question
Which state has the least densely packed molecules?
• Solid
• Liquid
• Gas
• Plasma

### Question 3

Question
Have a fixed volume
• Solid
• Liquid
• Gas
• Air

### Question 4

Question
Have a fixed shape
• Solid
• Liquid
• Gas
• Perfume

### Question 5

Question
How solids move around
• Osmosis
• Vibration
• Extremely quickly
• In a straight line until it hits the walls of the container

### Question 6

Question
Why does a solid expand upon heating?
• The mean size of each molecule expands with each change in degree Kelvin
• The air between the molecules exert a pressure that is equal in force to that of the solid molecules
• Increased vibration causes molecules to move away from forces of attraction, therefore occupying more space

### Question 7

Question
When the temperature of a solid increases then
• The volume increases
• The volume decreases
• The density increases
• The density decreases
• The mass decreases
• The mass increases
• Nothing at all changes

### Question 8

Question
Not easily compressed
• Solids
• Liquids
• Gases

### Question 9

Question
Shape affected by shape of container
• Solids
• Liquids
• Gases

### Question 10

Question
Why does't latent heat of fusion cause change in temperature
• The liquid is not being heated at all
• Potential energy changes instead of kinetic
• IS THIS A TRICK!?! Of course it changes temperature
• Not enough energy is absorbed

### Question 11

Question
True of Evaporation
• Surface phenomenon
• Occurs only at a specific temperature range
• Change from liquid to gas
• Increased when the surface area is increased
• Temperature does not affect it all
• Breeze increases the rate of evaporation
• Causes cooling of surface

### Question 12

Question
True of Boiling
• Surface phenomenon
• Occurs only at a specific temperature
• Change from liquid to gas
• The entire liquid is at 1 temperature
