From UCF Starbuck's, chapter 11 ideas (video)
Chantel gives her advice on how to handle the proportions in exercises 1 and 3, then Cherie describes her enjoyment of hydrogen "popping," which is in our textbook, p. 210.

Stefan-Boltzmann
Astronomers get a handle on the wattage per square meter of the surface of a star by using the Stefan-Boltzmann law, p. 109 of the PSM. By checking the spectrum of the star with a diffraction grating, they can estimate the temperature in Kelvins. Our star, the sun, has a surface temperature of about 5800 K. This means each square meter on the surface puts out about 64 million watts!

Isostatic piston
This exercise with an isostatic system, a piston in a cylinder, can be achieved in real life fairly easily. Just think of a standard piston that has a small weight on top of it, e.g., with mass 0.050 kg. The weight force is 0.49 N, no matter how high or how low the top moves. If the piston is rigid and has an area of, e.g., 0.000625 m2 (i.e., 2.5 cm x 2.5 cm) then it will add a pressure of 784 N/m2. That means that the weight ensures a common pressure of 784 Pa in the ideal gas.
