It would be easier to determine the effect of pressure on the dew point of nitrogen, as the dew point is actually a temperature.

You may want to clarify your question. In a sealed container, the dew point of nitrogen (or any gas) doesn't change. So, if your container of nitrogen is at a dew point of 10 degrees C, and you increase the temperature from 20 degrees to 50 degrees, the dew point remains at 10 degrees. The reason for this is because the dew point is actually the concentration of water molecules in the gas, and that remains constant with temperature.

1) This has to be inreference to the water content of N2 gas. As such, the water content determines the dew point, and overall system pressure has a bearing on this, as equilibrium vapor (water) pressure is affected by changes in mechanical pressure. [Look this up in a thermodynamics or physical chemistry book].

2) Temperature only matters in the sense that the system is above or below the dew point of this wet gas.

3) The actual water content of the gas has a direct influence on the dew point.
