Nitrogen State At Room Temperature

It is the fifth most abundant element in the universe and makes up about 78 of the earth s atmosphere which contains an estimated 4 000 trillion tons of the gas nitrogen is obtained from liquefied air through a process known as fractional distillation.

Nitrogen state at room temperature.

Over this temperature range liquid nitrogen looks much like boiling water. The temperature at which the liquid gas phase change occurs. Nitrogen density and specific weight online calculator figures and tables showing density and specific weight of nitrogen n 2 at temperatures ranging from 175 to 1325 c 280 to 2400 f at atmospheric and higher pressure imperial and si units. 320 f boiling point at sea level it is produced industrially by fractional distillation of liquid air it is a colorless low viscosity liquid that is widely used as a coolant.

Molecular nitrogen is bound by a trivalent bond which is one of the strongest in nature. The element nitrogen at room temperature is a gas. Below 63 k it freezes into solid nitrogen. Nitrogen was discovered by the scottish physician daniel rutherford in 1772.

A nitrogen atom has seven electrons. Density g cm 3 density is the mass of a substance that would fill 1 cm 3 at room temperature. The earth s atmosphere is made up of 78 nitrogen. However at low temperature and or high pressures the gas becomes a liquid or a solid.

We all breathe it all the time gasgas. The nitrogen phase diagram shows the phase behavior with changes in temperature and pressure. Because liquid nitrogen in a usual setting is boiling its usual temperature is 77 k. Liquid nitrogen ln 2 is nitrogen in a liquid state at low temperature 195 79 c 77 k.

The curve between the critical point and the triple point shows the nitrogen boiling point with changes in pressure. It has one of the highest electronegativities among the elements 3 04 on the pauling scale exceeded only by chlorine 3 16 oxygen 3 44. At normal atmospheric pressure nitrogen is a liquid between 63 k and 77 2 k 346 f and 320 44 f. Relative atomic mass the mass of an atom relative to that of.

The next most common gas is oxygen at 21. Nitrogen has a low melting and boiling point and is a gas at room temperature. It is represented by the symbol n and has an atomic number of 7 in the periodic table. Sublimation the transition of a substance directly from the solid to the gas phase without passing through a liquid phase.
