Problem P. 4688. (December 2014)
P. 4688. A thermally insulated container is divided into two parts by a wall of negligible volume. The volume of the two parts are 2 dm\(\displaystyle {}^3\) and 3 dm\(\displaystyle {}^3\). In the 2 dm\(\displaystyle {}^3\) part there is a sample of Helium gas at a temperature of 300 K and at a pressure of \(\displaystyle 2\cdot10^5\) Pa, and in the other part there is a sample of Oxygen gas at a temperature of 200 K and at a pressure of \(\displaystyle 10^5\) Pa. What will the temperature and the pressure of the mixture of gases if the wall is eliminated?
