Chapter 2: Kinetic Particle Theory

Question 1

Describe the kinetic particle arrangement of a solid.

Answer 1

Very strong forces of attraction between particles, very closely packed in an orderly manner, vibrating about their fixed positions with low energy levels.

Question 2

Describe the kinetic particle arrangement of a liquid.

Answer 2

Strong forces of attraction between particles, closely packed in a disorderly manner, particles slide past each other with moderate energy levels.

Question 3

Describe the kinetic particle arrangement of gas.

Answer 3

Weak forces of attraction between particles, far apart in a disorderly manner, move freely and rapidly in random, with the highest levels of energy.

Question 4

Why is the temperature constant in the middle of a heating/cooling curve?

Answer 4

Heating:
Because heat energy is taken in to overcome forces of attraction
Cooling:
Because heat energy is given out to form forces of attraction
