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.
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.
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 a relatively low melting point of around 80 degrees Celsius.
It has a melting point of 113 degrees celieus
Low relative to period 3 elements. 44 degree Celsius.
