___ cause pressure pulsations in a pipe line.

You have two containers of oxygen gas (O2). One container is filled with 1 mol of oxygen, the other container is filled with 2 mols of oxygen. The pressure of the gas in both containers is 1 bar and the temperature is 25 ºC. The change in entropy due to mixing, when the gas in both containers is combined into a single container at the same temperature and pressure is zero.

Consider the synthesis of methanol:

The following assumptions for an ideal gas are relaxed in the van der Waals model of a real gas: (1) the molecules do not attract each other (2) the molecules do not repel each other
