yes! its the Asthenosphere :D
Soap is made differently then other soap so there is no definite melting point
Magnesium sulfate has a high melting and boiling point, as it is made of Ionic bonds which are very strong. A lot of energy is needed to break them. So ionic compounds have high melting and boiling points. See related link for more information.
Virtually all minerals can be melted, when raised to high enough temperatures. But most minerals cannot be melted without some help besides open Sun. The temperature of melting depends on the atomic construction and composition of the mineral.
Most soup cans are not aluminum- they are tin plated steel. While the exact melting point will vary with the alloy used, it is ABOUT 1,350 degrees Celsius. It is MUCH higher than the melting point of aluminum.
The uppermost mantle is connected to the crust and forms the asthenosphere, which composes Earth's tectonic plates. The bulk of the mantle is composed of extremely hot rock under enormous pressure. The mantle may be very close to the melting point of the rock which composes it, or even partially melted. Mantle rock is higher in magnesium and iron than the crust. Rocks in the upper mantle are composed of the minerals olvine, garnet, spinel and pyroxene. With increasing depth, some of these minerals become unstable and are replaced by mineral polymorphs which have the same chemical composition, but different structures. For more information on the composition of the mantle as a whole, please see the related question.

A reamer is a tool, not a material. The melting point would depend on what material the reamer is made of.
Depends on what it is made of.
Knowing the melting point of a substance provides information to determine what the substance is if its unknown. If you are making a substance, checking the melting point will let you know if you have made what you set out to make, (because impurities can mess up the melting point)
Soap is made differently then other soap so there is no definite melting point
This can't be answered. It depends what the coin is made of.
Depends on what the solid is made of and what the temperature is. Sand is a solid and will stay outside forever in normal Earth temperatures without melting. Ice will stay outside forever if the temperature remains below freezing point.
It is made of tungsten, a metal with a very high melting point.
Melting points are of pure substances, not of objects made out of many, many substances. Eg. A news paper or an aeroplain don't have a melting point. Neither do batteries. But be carefull in warming them up above 50oC !!
atoms
The melting point of quartz is approx. 1 700 oc.
there are number of compounds having covalent bond and high melting point. Most common example is-diamond (Made of C)
