p-V diagram Sudoku time!

For the topic of Thermal Physics, JC1 students can try to make sense of p-V diagrams using the following exercise, which does not involve any calculation. They will need to fill in the cells in the table below with any of the three (+, - or 0) to indicate whether there is heat transfer, work done on the gas, or a change in internal energy.

Hooke's Law

Here are two applets students may like to try:

A. The first is a simple "experiment" showing that the extension of a spring is proportional to the force applied:


B. For the second applet, you can try:

  1. looking for the unknown masses.
  2. observing the potential energy at different extensions of each spring.
  3. varying the gravitational field strength.
