The heat of fusion is always less than the heat of vaporization because at the time of the phase change from solid to liquid, the molecules only require energy to escape from the crystalline network, but it preserves the other molecular junctions.

In the case of the phase change between liquid to steam, there must be a total breakdown of that intermolecular networks and therefore apply energy so that they are not again attracted by the conditions of their environment.

Do any individual air molecules travel the length of the tube? how do you know?

Ivanshal [37]

When a gas is inside the tube, the individual air molecules travel the length of the tube.

<h3>What is molecules?</h3>

The individual particle of a gas element moving randomly inside the element structure.

When the gas contained in a container, the molecules move randomly inside it. According to the kinetic theory of gases, molecules travel the mean distance. The air molecules vibrates horizontally parallel to the length of the tube.

In an open tube, air molecules are distant from each other. So, they can travel the length of the tube.

Thus, individual air molecules travel the length of the tube.
