PV Diagram for an Ideal Gas
GeoGebra link: https://www.geogebra.org/m/xyqhfvyw Applying the 1st Law of Thermodynamics to 4 simple changes on an ideal gas, students can check their understanding using this...
Stirling Engine
I bought a simple beta Stirling engine online at dx.com recently and it came in the mail today. It works well with a cup of hot water placed under it, although it might take a...
Can a Liquid Freeze and Boil Simultaneously?
Witness the freezing and boiling of a liquid take place at the same time. A thorough explanation for this observation is found here . Cyclohexane can both freeze and boil...
Adiabatic Process Demonstrations
Here are some interesting lecture demonstrations on adiabatic thermodynamic processes you can carry out. In an adiabatic process, there is no heat transfer between the system...
Heat Capacity of Water
Water has a high specific heat capacity of about 4200 J kg -1 K -1 . When a little bit of water is placed in a balloon, it is able to absorb a significant amount of heat from a...
Crushing Can
We are usually unaware of the immense strength of the pressure due to the atmosphere around us, having taken it for granted. This demonstration will utilize atmospheric pressure...
