Q:

# What are three basic assumptions in kinetic theory?

A:

The first assumption of the kinetic theory is that gas is made of identical molecules traveling in various directions. The second assumption is that the molecules do not lose energy when colliding with each other. The third assumption is that the energy transferred between the molecules is heat.

The kinetic theory of gases is based on a basic molecule of gas. It was developed by British scientist James Clerk Maxwell and Austrian physicist Ludwig Boltzmann. The kinetic theory was established in the 19th century and developed into an important concept of modern science.

The assumptions of kinetic theory bring the characteristics of gas molecules to a basic level. This allows for the measurement in a mathematical sense.

The three main points of the kinetic theory of matter are all matter consists of molecules and atoms; these molecules and atoms are constantly in motion; and as the temperature increases, the speed of the particles, and therefore the energy of the matter, increases. Each of these three points, once further explained, reveal how and why matter can change between the three phases of solid, liquid and gas.

Temperature is directly proportional to the average kinetic energy of the molecules in a substance. If the degree of motion of the molecules inside an object doubles, the temperature will also double.

The formula for average kinetic energy is one-half the mass times the square of the velocity. Using mathematical notation, the formula can be written as KE_avg = 1/2 x m x v^2, where KE_avg is the average kinetic energy, m is the mass, and v is the velocity.
