After students have measured the melting points of pure compounds, we move on to recrystallize an impure compound, such as benzoic acid mixed with copper(II) sulfate pentahydrate. This is a great opportunity to revisit the core chemistry idea that each pure substance has characteristic physical and...
II. Melting-points of aluminium, silver, gold, copper, and platinumThis article discusses fantasy football during 2006. The author offers excuses for fantasy players who find themselves out of their league playoffs, including the drafting of too many Oakland Raiders players, confusion at the Denver...
Less popular than gravity die-casting, and tends to be used purely for the production of car wheels. Gives lower production rates. • Slush casting: for creating hollow parts without cores in low-melting-point metals such as lead, zinc and copper alloys. View chapterExplore book Low melting...

High melting point metallic, e.g., steel mold members are facilely and inexpensively produced by depositing, e.g., flame-spraying, droplets of a melt of a metal having a high melting point onto the fr
The sensible energy in the PCM increases very sharply at the beginning of the charging process as walls transfer the heat and the fins store this in the form of sensible heat (the initial temperature of the PCM is below the melting point, as shown in Equation (20) and Table 2). The ra...
The variation in pulse numbers has minimal impact on the position of the melting region boundaries and the distribution of the liquidus point. However, for the temperature-dependent thermophysical parameter group in Figure 8d–f, more energy is transferred to a deeper position. Moreover, after the...
This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation ...
Physical constants for more than 280 common inorganic compounds. Density is given for the actual state at 25°C and for liquid phase at melting point temperature.
We propose the theoretical description for the temperature and concentration phase transformations in composite lithium grease doped with the mesogenic additives of the copper(II) carboxylates family, copper(II) valerate and isovalerate, in the concentration range 1, 5, 10, 20 wt. percents. The ...
