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 else can I help you with?
Its low melting point is useful in automatic sprinkler systems?
The low melting point of a material used in automatic sprinkler systems helps it to quickly release water when exposed to heat, activating the sprinkler system. This property ensures rapid response and effective fire suppression.
What material is useful for making molds because it has a low melting point?
Materials with low melting points like tin, bismuth, or low-melting point alloys are ideal for making molds. These materials can easily be melted and poured into a mold to create detailed and intricate shapes.
Naphthalene has high or low melting point?
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
Does sulfur have a high or low melting point?
It has a melting point of 113 degrees celieus
Does fluorine has a high or low melting point?
Fluorine has a very low melting point of -219.67 degrees Celsius. It is the lightest halogen and exists as a gas at room temperature.

Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Does sulfur have a high or low melting point?
It has a melting point of 113 degrees celieus
What is specific resistance and melting point of fuse?
low resistivity and low melting point.
Does chlorine have a high melting point low boiling point etc?
Chlorine has a low melting point of -100.98°C and a low boiling point of -34.6°C.
Why technetium and manganese have low melting point?
The melting point of technetium is 2 157 0C- it is not low.
Does carbon have high melting point?
it has a low melting point
Does polonium have a high or low melting point?
