Which flask contains the most molecules if each of these flasks is of the same size and kept at the same temperature?

Based on the given, the flask with the most molecules is task 4. The answer will be based on Boyle’s Law. It states that a fixed amount of ideal gas is placed at a certain temperature, the pressure and the volume will be inversely proportional.

This means that they will always have an inverse relationship with each other. If you would check the number of molecules that are available for each flask, you can see that they all have different amounts. Out of the 4, the 4th flash has the highest amount of pressure which also means that it has the most molecules present. The high level of molecules is causing pressure against the flask.

Here, Flask 4 contains the most molecules. Hence, the correct option is 4.

As per the Boyle’s gas law, if a fixed amount of an ideal gas is kept at a fixed temperature, then the resultant pressure and volume are inversely proportional to each other. Or we can also say that Boyle’s law also states that pressure and volume of a gas will always have an inverse relationship with each other if they are kept at constant temperature.

In Flask 4, the pressure is very high as compared to other flasks and due to this, it has the most molecules.
