Depends on the kind of solder.
Solder needs a low melting point to protect heat seaitive componanats from damage. Also, in plumbing, solder is more liquid when applied, thus it distrinutes more evenly making a better seal
The melting point depends on the solder. The lowest I've seen is 395F.
- Melting point change. ^.^
Melting point is an intensive property. Regardless of the amount of a substance present the melting point will remain the same.
Low melting pointsolder used for PC boards is a must. The components on the board are heat sensitive and can be destroyed by high heating when they are soldered to the PC board traces. This is mostly done by machines now but the solder still has to be the lowest melting point possible.
It has a low melting point but has excellent electrical conductivity.
Melting point is a physical property, not a change.
The melting point of solder is around 300 degrees C. The low melting point is the reason it is useful for soldering.The melting point of solder will depend on what the solder of composed of. The most common solder has a melting point of 361.4 degrees F.
The melting poit is 183 0C; the boiling point is not determined.
does the melting point of a substance change over time
It just means that one liquid can be distinguished from another by its boiling point because it is a characteristic or property of that particular liquid.
