Question 1
Question
What does the kinetic theory of matter state?
Answer
-
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?
Answer
-
Solid
-
Liquid
-
Gas
-
Plasma
Question 3
Question
Have a fixed volume
Answer
-
Solid
-
Liquid
-
Gas
-
Air
Question 4
Question
Have a fixed shape
Answer
-
Solid
-
Liquid
-

-
Perfume
Question 5
Question
How solids move around
Answer
-
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?
Answer
-
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
Answer
-
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
Answer
-
Solids
-
Liquids
-
Gases
Question 9
Question
Shape affected by shape of container
Answer
-
Solids
-
Liquids
-
Gases
Question 10
Question
Why does't latent heat of fusion cause change in temperature
Answer
-
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
Answer
-
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
Answer
-
Surface phenomenon
-
Occurs only at a specific temperature
-
Change from liquid to gas
-
The entire liquid is at 1 temperature
