Question

which of the following is true regarding the size of gas molecules, according to the kinetic molecular theory?
select the correct answer below:
the size of the molecules is small but cannot be neglected.
the size of the molecules is so small compared to the distance between them that the size is taken to be negligible.
the distance between molecules is small, so their size is taken to be negligible.
the size of the molecules depends on the temperature.

Explanation:

According to the kinetic molecular theory, gas molecules are considered to have negligible volume compared to the large distances between them. This is a fundamental assumption of the theory.

Answer:

The size of the molecules is so small compared to the distance between them that the size is taken to be negligible.
