Raising the Pressure Inside a Flask: A Fun Experiment to Try

How can you increase the pressure inside a closed flask?

A closed flask of air (0.250 L) contains 5.00 "puffs" of particles. The pressure probe on the flask reads 93 kPa. A student uses a syringe to add an additional 3.00 "puffs" of air through the stopper. Find a new pressure inside the flask.

Solution:

New pressure inside the flask would be 148.8 kPa.

Have you ever wondered how to increase the pressure inside a closed flask? Well, here's a fun experiment that you can try at home or in the laboratory!

In the given scenario, the initial pressure inside the flask was 93 kPa with 5 "puffs" of particles. By adding an additional 3 "puffs" of air, the new pressure inside the flask increased to 148.8 kPa. This demonstrates how increasing the number of particles in a closed system can raise the pressure within it.

The increase in pressure can be attributed to the ideal gas law equation, which relates the pressure, volume, number of moles, and temperature of a gas. By keeping the volume and temperature constant, adding more particles (in this case, "puffs" of air) leads to a higher pressure.

So, next time you want to impress your friends with a simple yet fascinating experiment, try adding some "puffs" of air to a closed flask and see how the pressure inside changes!
