No, materials do not melt at the same temperature. An example would be cooking oils. Some burn at lower temperatures than others.
You could possibly arrange an experiment for different substances to melt and boil at the same time, but they would not do so at the same temperature. Different substances have different properties, they do not all melt and boil at the same temperature.
because they are made from different molecules and elements. It's like asking why are some materials harder than others.
As all the ice does not melt then the temperature must be 0'C (assuming uniform temperature of the block and that the rivets remain in thermal contact with the remaining ice.)
Yes
no
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.

yes
Yes, a mineral can not droop or melt .
The rocks will melt when they reach the proper temperature, usually thousands of degrees.
False, all minerals DO NOT have the same melting point
it all depends on the temperature. ice melts faster at higher temperatures
It depends on the substance and not in temperature, we have gas (oxygen) we can have liquid (water, H2O) and we can have ice... that will melt
No
No all solids do not expand at same rate because some solid expand at less temperature and some solids expand at less temperature. For example if we take iron and plastic iron expands at high temperature and plastic melt at less temperature(at candle light also).
