Aerosol cans allow liquids to come out of their interior in the form of jets. But what factors contribute to this happening? The high pressure inside the container is what determines its use.

What causes the spray effect?

By pushing the pin down, we open the passage from the inside to the outside of the can. The propellant gas contained is liquefied due to the high pressure in the container, and at this instant it is propelled out through the nozzle. The shape of the nozzle (very narrow orifice) causes the liquid to be sprayed in a fine spray.

The gas pressure inside the can is different from the outside pressure, that is, the pressure inside the container is greater than atmospheric pressure.

Applying to the concept “Gas Law”:

A gas can undergo three types of state variables: its volume, its temperature and its pressure. The equation below reflects these variations:

[tex]\frac{p1.v1}{t1}=\frac{p2.v2}{t2} \\[/tex]

This is known as the general gas equation, it addresses the three state variables (P, V, and T).

To understand this statement, see a practical example: why is it dangerous to leave empty spray cans exposed to heat?

If we slightly heat an empty can and press its valve, we will notice that there is still a certain amount of gas left. In the presence of fire (high temperatures), the remaining gas expands in such a way that it causes the can to explode.

As P, T, V are proportional quantities, the increase of one influences the increase of the other. Therefore, we have an increase in temperature and consequent increase in volume and pressure.

This is why this object, when discarded, cannot undergo incineration (burning).

With this information, we can point out that the answer C is the correct one because it states that...

C) The molecules move faster causing the pressure to increase and the can to explode.

With this information we know that the pressure increases when the aerosol can is placed at high temperatures, so I am careful with your aerosol cans
