    Graduate Can Entropy Be Reduced in a Spontaneous Thermodynamic Process?

    Hi! I have a practical problem that causes me to wonder. It seems like I have to choose from gaining energy from nothing, or to get a reduction in entropy from a spontaneous process. Imagine a small enclosed chamber filled with dry H2O gas. The properties are: 0.5 Bar 8.0 kJ/(kg*K) 200C...

    Graduate What happens to entropy when mixing two gases with different properties?

    I thought this was an easy one... Should I expect more response if it was posted in the Classical Physics section?

    Graduate What happens to entropy when mixing two gases with different properties?

    Hi, I am new here, so please direct me if I am posting completely wrong here. Imagine a small enclosed chamber filled with dry H2O gas. The properties are: 0.5 Bar 8.0 kJ/(kg*K) 200C 2850kJ/kg An infinitely large reservoir of H2O gas has the following properties: 1.0 Bar 8.0kJ/(kg*K)...
