Temperature and Pressure of Gas
This interactive HTML5 simulation models the behavior of gas particles in a fixed-volume container, allowing users to explore the relationships between temperature, pressure, and...
12 Temperature and Ideal Gases
Pressure and Projectile - Penguin's Poop
An interesting paper on the range of penguin's poop. Their motivation? "Such information is useful for keepers to avoid the direct hitting of faeceses." Source:...
Which Equations Apply Only to Ideal Gases?
Students are sometimes unclear about which of the equations taught in the topic of Thermal Physics apply to ideal gases and which apply to all systems (whether ideal or real gas,...
Boyle's Law
Using a hand-operated vacuum pump, we can demonstrate the relationship between pressure and volume of a gas. According to Boyle's law, the pressure of a gas of constant mass and...
Boiling under Reduced Pressure
With the help of a simple manual vacuum pump that is used to keep food fresh, we can demonstrate the effect of a reduced pressure on the boiling point of water. This leads...
Egg out of Flask
In a previous demonstration , we put a boiled egg into a flask with a mouth narrower than the egg. The challenge is now to remove the egg from the flask without breaking it....
Egg into Flask
This classic physics demonstration is used to show the effects of pressure difference between the atmosphere and a cooling volume of air. With a set of clean apparatus, you can...
