Its low melting point is useful in automatic sprinkler systems?
iy's low melting point is useful in atomatic sprinkler systems
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.
Why is it important for the melting point of the solder in a fire sprinkler to be lower then its melting points of the parts it connects?
If the solder melted sooner than the surrounding parts, the line carrying the water to the sprinkler would lose pressure, resulting in the failure of the sprinkler system to deliver water.
Why are properties useful?
Density Solubility Buoyancy Melting Point Boiling Point Odor Flammability
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 are the useful physical property used to identify an organic compound?
For example the melting point.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
Which transition metal is useful due to its extremely high melting point.?
You think probable to wolfram (W).
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
The temperature at which a solid melts is called?
melting point
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
