You would do this because you have to know how much heat it can handle to be able to have people use it
You would want a product that can withstand the heat you intend it to be exposed to plus some, as a safety factor. You wouldn't want to make an engine if it will melt down the highway. Suppose just the surface of the part starts to melt under high enough temperature. Then if the liquid metal gets 'slung away' by the moving parts, then the part no longer has the same shape, strength and other characteristics that is is designed to have. A frying pan would have the same concern. If just a little of the pan melted while you're frying an egg, what happens to the liquid metal? Does it get mixed in with the egg, then you end up eating it...
Because I'm a rizzeler
Because it metal
No
Melting is a phase change in which a substance changes from the solid state to the liquid state. Changing phases is also a physical change.
The melting point of a substance varies according to the properties of that substance
what is the melting point and boiling point of substance
This is the definition of the melting point of an element or substance. The melting point is when a solid begins to turn into a liquid. A substance also has a boiling point and freezing point.

Yes, impurities have important effects on the melting and boiling point of materials.
Melting and boiling points are physical properties of materials.

it decreases.
melting
It indicates that the substance has turned to a liquid.
what the heck are you asking? the melting point is not a substance. it's a temperature in which the substance starts to melt
The melting point of a substance varies according to the properties of that substance
what is the melting point and boiling point of substance
does the melting point of a substance change over time
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
