Based on the kinetic molecular theory, which of the following statements is correct about the particles in a sample of gas? They have negligible kinetic energy. There is negligible force of attraction between them. The space between them decreases with increase in temperature. Their average kinetic energy decreases with increase in temperature.

Respuesta :

Answer:

There is negligible force of attraction between them.

Explanation:

According to kinetic molecular theory of gases:

a) They have high kinetic energy so the molecules show random motion.

b) The space between them increases with increase in temperature. With increase in temperature, the kinetic energy increases and the molecules move farther from each other, volume increases.

c) the average kinetic energy increases with increase in temperature

Thus only true statement is:

There is negligible force of attraction between them.

Based on the kinetic molecular theory, there is a negligible force of attraction between the particles in the sample of gas.

The correct statement is option B.

What kinetic molecular theory?

Kinetic molecular theory state that the particles of gas are large spherical and are in constant motion and have a perfectly elastic collision.

This theory can explain both Boyle's law and Charles's law.

Thus, the correct option is B, There is a negligible force of attraction between them.
