I have a different explanation for Crookes Radiometer. It relies on the fact that when there is a temperature difference between the gas and it's boundary, gas molecules will bounce with increased speed (that is how heat is transferred from boundary to gas). This increase in speed will exert a...
I have derived that, when there is a temperature difference (gradient) in a gas (consider a long tube with one end maintained at 100oC and other end maintained at 0oC), there will be a pressure gradient (something similar to Bernoulli's law).
