In China, there were many different weighting standards of tael depending on the region or type of trade. In general the silver tael weighed around 40 grams (1.3 ozt). The most common government measure was the Kuping (庫平; kùpíng; 'treasury standard') tael, weighing 37.5 grams (1.21 ozt
Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...

Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C, a tremendous amount of force can be generated if liquid nitrogen is rapidly vaporised in an enclosed space. In an incident on January 12, 2006, at Texas A&M University, the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed. As a ...

Many gases can be put into a liquid state at normal atmospheric pressure by simple cooling; a few, such as carbon dioxide, require pressurization as well. Liquefaction is used for analyzing the fundamental properties of gas molecules (intermolecular forces), or for the storage of gases, for example: LPG , and in refrigeration and air conditioning .
Additionally, the kilobar, weighing 1,000 grams (32.15 troy ounces), and the 100-troy-ounce (109.7-ounce; 6.9-pound; 3.1-kilogram) gold bar are popular for trading and investment due to their more manageable size and weight. [1] These bars carry a minimal premium over the spot price of gold, facilitating small transfers between banks and ...
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2]
