The silver never actually "melts" -- unless you overheat it, of course. First, the binder burns off, and then the silver particles bond together in a process called "sintering." If the piece goes bright and shiny and shimmering, then you have overheated it and started it to melt. You don't want that.

Don't know - ages - there's about 30 million cubic kilometres of ice in Antarctica. Enough to cover the whole of Australia to a depth of 4 km. See similar questions...

The melting temperature remains 210°C for both. Fittings are manufactured using a moulding technique (the material is pressed inside the mould), whereas the pipe is extruded (namely, the material is drawn), therefore the pipe reaches the melting temperature a few seconds before the fitting.

The higher the temperature, the faster the fermentation process, and the faster the sugar will be used up and converted into acid. See similar questions...

While aluminum alloys melt at temperatures typically over 1000°F, their properties can change significantly at much lower temperatures. The answer to this question is dependent not only on the property variation with temperature of the alloy and temper of interest but also on the requirements of the specific application. As a rough rule of thumb, aluminum alloys do not show significant property changes at temperature below 200 , but will lose strength with time at higher temperatures. See similar questions...

The many advantages of aluminum are not impaired by exposure to low-temperatures. Aluminum actually gains strength as temperature is reduced, making it a most appropriate material for arctic, space or cryogenic applications. A useful publication is Aluminum Alloys for Cryogenic Applications, available from the Aluminum Association. See similar questions...

In temperatures over 72 degrees, our chocolate dipped/drizzled biscotti will melt. Also, chocolate dipped/drizzled biscotti will melt if kept inside a hot vehicle or direct hot sunlight, even if left for a few minutes. Think of our biscotti as a really nice box of chocolates from a specialty candy store. YOU ARE ORDERING THE BEST. Montione's Biscotti uses a very high quality, delicious tasting chocolate that we temper prior to dipping. See similar questions...

There is no explanation given in The Wizard of Oz as to why water dissolved and destroyed the Wicked Witch of the West. The only indication might be in an incident when Toto bites her: "The Witch did not bleed where she was bitten, for she was so wicked that the blood in her had dried up many years before." Many believe that she had extended her life through magical means for so long that there was actually very little of her left, and so the water was enough to finally break her down.

Depending on the type of glass and on the glass batch composition the melting temperature is between approximately 1000 ?C and 1600 ?C (1832 ?F and 2912 ?F). See similar questions...

No they do not. The lamps are made out of true Himalayan Salt Crystal that was formed inside of the Himalayan mountain ranges over 250 million years ago. They do not melt or wear out. With the proper care, their crystals will continue to stay in tact for many more lifetimes to come. The negative ions are generated when heat is applied. Each lamp comes with a light bulb, both for illumination and to generate the heat necessary to activate the ions. See similar questions...

The Loctite Glue Gun operates up to a temperature of 170°C so we always advise that you handle the product with care and attention and keep it out of the reach of children See similar questions...

Aluminum and its alloys are normally protected by an ultra thin surface oxide film (known as the passive film) and are reasonably resistant to corrosion in environments having a pH of 4~8. In acidic or alkaline environment, the oxide film is no longer stable and aluminum corrodes actively, forming soluble corrosion product (Al3+ or AlO2-). See similar questions...

quot;Coagulation" is an important water treatment process for its human consumption, because there is no another way of eliminating the turbidity of raw water. This technology requires the addition of substances that through a physico-chemical mechanism permits the gathering of small and light particles. The added particles produce bigger ones (called "floccules") that are easily eliminated by decantation. See similar questions...

Thermal Window frame and an ordinary aluminum window frame on extremely cold dry ice to illustrate how cold is transferred through the frame. Notice that the ordinary aluminum window frame, shown on the left, is completely covered with frost. Now look at the West-Prime Thermal Window Frame on the right. Our thermal barrier resists the transfer of cold from the outside to the inside of the frame. And, of course, the same thermal barrier slows the transfer of heat in summer. See similar questions...

No. The Taser utilizes compressed nitrogen (an inert gas). The Taser compressed air capsules have successfully held their charges at temperatures of minus 20? F and up to 160? F. Moreover, altitude will not adversely effect the firing of an Taser. In addition, the temperature will not effect the T-Wave. However, as with any product containing polycarbonates and other thermoplastics, the Taser and Air Cartridges should never be left in direct sunlight._________________________________ See similar questions...

Curie Temperature (Tc): This is the temperature at which a magnet material loses it's strength, permanently. Another useful number (if available) is Tmax, the recommended maximum operating temperature. Above Tmax (around 266 deg. F for most NdFeB magnets) a magnet will start ot lose its power, and at Tc all power is lost. If you need strong magnets that can be used at high temperatures, consider using Samarium Cobalt (SmCo) magnets. See similar questions...

The temperature in the lower part of the atmosphere (the troposphere) decreases as elevation increases. The average temperature decreases from 15?C at the bottom of the atmosphere to -60?C at the top of the troposphere. The lower part of the atmosphere in which temperature decreases with height is called the troposphere. The height of the troposphere ranges from 18 km in the tropics to 12 km near the poles. The rate of temperature decrease with height is called the lapse rate. See similar questions...

The process of evaporation happens all the time. Our bodies, for example, perspire in hot weather. Through evaporation, sweat dries and causes our body temperature to drop. Whenever dry air passes over water, some of the water will be absorbed by the air. That is why evaporative cooling naturally occurs near waterfalls, rivers, lakes and oceans. The hotter and drier the air, the more water that can be absorbed. See similar questions...

It may be to do with the volume of the case falling (due to the addition of materials), and the average residence time of air being reduced. The void space inside the case is reduced, but the airflow is still maintained at virtually the same rate by the PSU and other fans (if any) - so there is a faster airflow over warm components - thus they can actually run cooler. The materials have the effect of 'ducting' cooler air over the internal components. See similar questions...
