What has a low melting point and is useful in sprinklers?
modern automatic sprinklers use a glass bulb that is filled with a fluid that boils and expands at a preset temperature. the glass bulb has a small bubble in the fluid. when a fire causes the fluid to boil, it shatters the glass bulb, which is keeping the waterway seal of the sprinkler in place. When the seal is gone, water can flow through the sprinkler orfice, and extinguish the fire. older sprinkler models use a link and lever arrangement, with a link of solder that melts at a preset temperature. The link and levers of the sprinkler mechanically hold the waterway seal of the sprinkler closed. When the link melts, the mechanical seal is gone, and water can flow through the orfice.
What material is useful for making molds because it has a low melting point?
waxWax
How do you prove that glucose do not raise the melting point of stearic acid?
No, impurities do not raise the melting point of Stearic Acid, they decrease it. All impurities decrease the melting point of solids.
What element Used in the making of supersonic airplane wings aritficial joints for bones and submarine hulls?
Titanium and alminium are both useful for these tasks, as they have high melting pointsand don't easily corrode.
What makes a substance a special kind of stuff?
Substances become special because they have useful properties. Tungsten has an extremely high melting point, which makes it useful as a filament in incandescent light bulbs. Oxygen supports combustion and metabolism. Glass is valued for being transparent as well as waterproof, strong, and durable. And so forth.

How are impure substances useful for mankind?
When it snows in certain countries of the world the government sprinkles salt over the snow so that the melting point of the snow decreases melting it more quickly.This is one example where impurities are useful to mankind
