Question

Which is not consistent with the kinetic molecular theory (KMT) of gases?

O The Celsius temperature is a measure of the average kinetic energy of the gas particles.
O There is no loss in kinetic energy when the particles collide.
O Gas particles are in constant, random motion.
O Gas particles are assumed to be very small compared to the empty space around them, or the distance separating the particles.

Answer 1

The statement that is not consistent with the kinetic molecular theory is that there is no loss in kinetic energy when the particles collide.

Step-by-step explanation:

The kinetic molecular theory (KMT) of gases has five basic assumptions that explain the behavior of gas particles:

1. Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. The particles of a gas may be either atoms or molecules.
2. Gas particles are in constant rapid motion in random directions. The fast motion of gas particles gives them a relatively large amount of kinetic energy.
3. Collisions between gas particles and between particles and the container walls are elastic collisions. There is no loss in kinetic energy when the particles collide.
4. There are no forces of attraction or repulsion between gas particles.
5. The average kinetic energy of gas particles is dependent upon the temperature of the gas. As the temperature of a sample of gas is increased, the speeds of the particles are increased, resulting in an increase in their kinetic energy.

Based on these assumptions, the statement that is not consistent with the kinetic molecular theory is:

There is no loss in kinetic energy when the particles collide
