chpt 3 kinetic particle theory

Question 1

What are the arrangement of particles in a solid ?

Answer 1

1. very closely packed together in an orderly arrangement
2. vibrate about in their fixed positions
3. cannot be compressed
4. cannot flow

Question 2

What are the arrangement of particles in a liquid ?

Answer 2

1. closely packed in an disorderly arrangement
2. move freely throughout the liquid
3. cannot be compressed
4. flows easily

Question 3

What are the arrangement of particles in a gas ?

Answer 3

1. very far apart in a disorderly arrangement
2. move about freely and randomly at high speeds
3. can be compressed
4. flows in all directions

Question 4

What are the factors affecting rate of diffusion ?

Answer 4

1. temperature
   higher temp -> higher kinetic energy of particles -> faster movement of particles
2. relative molecular mass of particle
   greater RAM of particle -> slower rate of diffusion
