Generally, yes
When pressure on a gas increases, its temperature also increases. This relationship is described by the ideal gas law (PV = nRT), showing that an increase in pressure leads to an increase in temperature to maintain the same volume and number of moles of gas.
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
to increase the boiling point of the coolant
Solubilty of gases in water increase when the temperature decrease, For nitrogen you can see an infographics at this link.
You can separate nitrogen gas from liquid nitrogen by allowing the liquid nitrogen to evaporate at room temperature or by heating it to increase the rate of evaporation. The nitrogen gas will separate from the liquid nitrogen as it evaporates, leaving behind the liquid nitrogen.
Pressurised coolant boils at a higher temperature than unpressurised
Yes, the pressure of nitrogen gas will change with temperature according to the ideal gas law. As temperature increases, the pressure of nitrogen gas will also increase, assuming the volume and amount of gas remain constant. Conversely, a decrease in temperature will result in a decrease in pressure, as long as other factors remain constant.
Yes, nitrogen gas expands with an increase in temperature and contracts with a decrease in temperature. This behavior is consistent with the ideal gas law, which describes the relationship between pressure, volume, temperature, and quantity of gas.
The pressure inside of a container when nitrogen gas is added depends on:what the pressure was before the gas was addedhow big the container ishow much nitrogen gas is addedthe temperature of the gas before it is addedthe temperature of the container and its contents
Nitrogen can be obtained as a solid at very low temperature, under -210 0C. At room temperature nitrogen is a gas.
It doesn't. Harvesting removes soil nitrogen
Nitrogen gas is not in itself flammable, and does not have an auto ignition temperature.
