7. Kinetic Particle Model of Matter Flashcards
1
Q
What is the kinetic particle model of matter?
A
It is made up of tiny particles that are in continuous motion
2
Q
More energy in particles means.
A
Vibrate more vigorously
3
Q
Energy in kinetic store+ energy in potential store = ?
A
Energy in internal store
4
Q
Which state has the highest density?
A
solid
5
Q
Why can the particles in the liquid state slide over each other without fixed position?
A
As they have weaker force to hold the particles together
6
Q
Gas particles are far apart and irregular, this giver the particles ?
A
the most energy among all 3 state
7
Q
When temperature increase, does kinetic energy increase or decrease?
A
increase
8
Q
In a graph for change of states, what does the horizontal line represents?
A
- Melting
- Boiling
- Freezing
- Condensation
