## Homework Statement

Two isolated containers, of volumes V

_{1}and V

_{2}, enclose

**ideal single atom gas**at the same pressure p. The number of particles in each container is equal, the temperature of gas in container one is T

_{1}=293K and the temperature of gas in container two is T

_{2}=308K. An equilibrium is acheived by connecting the two containers. Calculate the entropy of the system if each container initially contained 100 mol of gas.

## Homework Equations

dQ=dE+dW

dS=dQ/T

dE=3/2 nRdT

pV=nRT

## The Attempt at a Solution

Basically, I've solved the problem, with the result of (delta)S=1153.77 J/K. Mathematically speaking, it checks out, but I doubt, along with a few of my colleagues, that the result is much too great. I've also searched the wikipedia for the order of magintudes which shows that the standard entropy of 1 mole of graphite is 5.74 J/K. This means that, for 200 moles of the gas, the result should be more or less accurate.

I'd greatly appreciate if anyone could double check this. Thank you :)
