The Science:Because the boiling point of liquid nitrogen is -196 degrees Celsius, at room temperature the liquid instantly starts to change phase into a gas. The gas fills up more volume than the liquid and starts to increase the pressure inside the container. In fact the expansion rate is ...

Nitrogen is the most important, limiting element for plant production. Biological nitrogen fixation is the only natural means to convert this essential element to a usable form.
aNitrogen is an inert gas, but at a high temperature can and file, calcium, magnesium and oxygen. Nitrogen can be liquefied, condensed into liquid nitrogen. Nitrogen so can be applied to oil industry is suitable for physical reasons, its chemical properties, a guaranteed source, low cost. 氮...
PCC6803 by using single-molecule spectroscopy at liquid‑nitrogen temperatures. Fluorescence emission at around 720 nm from the red Chls in single PSI trimers was monitored at 80–100 K. Intermittent variations in the emission intensities, so-called blinking, were frequently observed. Its ...
This is why we have to apply pressure to solid samples using an anvil, but not to liquids, to collect the spectra. Figure 5 illustrates some scenarios at the crystal–sample interface that might affect the reproducibility of the resulting IR spectra. For example, there is a limit to how ...
Polynitrogen molecules are attractive for high-energy-density materials due to energy stored in nitrogen–nitrogen bonds; however, it remains challenging to find energy-efficient synthetic routes and stabilization mechanisms for these compounds. Direct s
It is defined as the boiling point of a liquid, at the temperature at which its vapor pressure is equal to the pressure of the gas over the liquid. As the temperature is increased, the vapor pressure increasesAnswer and Explanation:
This is much higher than the value from elemental analysis, therefore it confirms that nitrogen is adsorbed on the surface, rather than incorporated in the bulk. The deconvolution of N1s peak of k50am (Fig. 5b inset) reveals the presence of an intense peak at 399.5 eV which is ...
Cryotherapy with liquid nitrogen is the most effective method to remove common warts, found a study published in CMAJ (Canadian Medical Association Journal).
