lesson 1

Question 1

explains the properties of gas, solids, and liquids in terms of intermolecular forces of attraction and the kinetic energy of the individual particles.

Answer 1

Kinetic Molecular Theory

Question 2

The Kinetic Molecular Theory states that:

Answer 2

1. All matter is made of tiny particles. These particles are in constant motion.
2. The speed of particles is proportional to temperature.
3. Solids, liquids, and gases differ in distances between particles, freedom of motion of particles, and the extent to which the particles interact.

Question 20

A bond that
involves the
sharing of
electrons to form electron pairs
between atoms.

Answer 20
