kinetic particle theory Flashcards
1
Q
what does kpt state?
A
that all matter is made up of tiny particles and these particles are always in constant and random motion
2
Q
particles of a solid
A
- very closely packed together in an orderly manner
- vibrate about their fixed positions and have very low kinetic energy
- held together by very strong forces of attraction
3
Q
particles of a liquid
A
- held together by moderately strong forces of attraction
-particles slide past one another - closely packed in a disorderly manner
4
Q
particles of a gas
A
- far apart in a disorderly manner
- particles move quickly and randomly in any direction
- particles are held together by very weak forces of attraction
5
Q
what is diffusion?
A
diffusion is the net movement of particles from a region of higher concentration to a region of lower concentration
6
Q
conditions that affect the rate of diffusion
A
- effect of temperature
- effect of particle mass
7
Q
effect of temperature on the rate of diffusion
A
diffusion occurs faster at higher temperatures as the particles possess greater kinetic energy. (more kinetic energy = more movement)
