Explain the trend in melting point of metals across period 3 elements. Why does water boil at a higher temp then NH_3 when they are both dipoles? Why would HF have a lower electrical conductivity than NaCl? Magnesium is a very volatile element like sodium, but sodium burns vigorously in ...
After dipping all piled scrap below the bath surface level, only oxygen-containing gas of blowing quantity less than the gas blow-through limit decided by the depth of molten metal, is blown from the furnace bottom tuyere to decarburize the molten iron and raise the temp. 展开 ...
An agglomerate made up of iron ore, coal and a bonding agent is introduced into the top part of a cupola furnace. The agglomerate is allowed to stream downwards and is subsequently heated to a temp. above 1000 deg.C by gases flowing through the furnace. The charge is converted into ...

Metal–organic frameworks (MOFs) are microporous materials with huge potential for chemical processes. Structural collapse at high pressure, and transitions to liquid states at high temperature, have recently been observed in the zeolitic imidazolate framework (ZIF) family of MOFs. Here, we show that...

Why does water boil at a higher temp then NH_3 when they are both dipoles? Why does the boiling point of liquids vary with altitude? Explain the trend in melting point of metals across period 3 elements. What is the effect of impurities on the melting and boiling points of a...
PURPOSE:To prevent the hole digging effect of a molten metal and to efficiently and safely melt and evaporate the metal in a crucible by monitoring the temp. of a crucible material and controlling a focusing coil to adjust the focus of an electron beam flux. CONSTITUTION:The electron ray flux...
