Frage 1
Frage
What does the kinetic theory of matter state?
Antworten
-
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
Frage 2
Frage
Which state has the least densely packed molecules?
Frage 3
Frage
Have a fixed volume
Frage 4
Frage 5
Frage
How solids move around
Frage 6
Frage
Why does a solid expand upon heating?
Antworten
-
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
Frage 7
Frage
When the temperature of a solid increases then
Antworten
-
The volume increases
-
The volume decreases
-
The density increases
-
The density decreases
-
The mass decreases
-
The mass increases
-
Nothing at all changes
Frage 8
Frage
Not easily compressed
Frage 9
Frage
Shape affected by shape of container
Frage 10
Frage
Why does't latent heat of fusion cause change in temperature
Antworten
-
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
Frage 11
Frage
True of Evaporation
Antworten
-
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
Frage 12
Antworten
-
Surface phenomenon
-
Occurs only at a specific temperature
-
Change from liquid to gas
-
The entire liquid is at 1 temperature
