A 11.0L gas tank containing 4.00moles of ideal He gas at 20.0?C is placed inside a completely evacuated insulated bell jar of volume 40.0L . A small hole in the tank allows the He to leak out into the jar until the gas reaches a final equilibrium state with no more leakage.
What is the change in entropy of this system due to the leaking of the gas?

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
