Know the Answer?

Diamond Thornton · Answer 1

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.

Carissa Beard · Answer 2

The correct answer is that there is negligible force of attraction between them. This is because the gas molecules are long distances apart distances that increase with increase in temperature. The inter molecular force of attraction also decreases with the increase in temperature.
