chemical because you are able to turn it into a solid again adn melt it again and agian and it can be changed to origanal state. :)

What are the physical and chemical properties of solder?
Solder is a mixture of various metals. Its physical property is that it melts at fairly low temperatures, not so low that it melts when this is undesired. Its reactions are the same as the component metals.
Special property of solder?
Solder has a relatively low melting point, and it wets many different metals allowing it to be used to join (solder) them together. It is also fairly resistant to corrosion when the correct solder alloy is applied to the work. We see a lot of solder used in electrical and electrical applications, so it's a fairly good electrical conductor.
What is the chemical formula for solder?
Since solder is an alloy, there is no specific formula for it. It consists of 60% tin and 40% lead. By - Yash Shah Student NESSS, Vadodara
What is the subsatnce is used to join metals together such as pipes?
Solder. It is an alloy of lead and tin, with a (relatively) low melting point. It only works with Copper or lead pipes.
Solder - lead and tin uses?
A solder is a metal or alloy that has a melting point range of 90 to 450 degrees Celsius (200 to 840 degrees Fahrenheit). The melting point range makes sure that the metal or alloy is easily handled at room temperature, can be melted to join other metallic surfaces when a moderate amount of heat is applied, and returns to a solid state when it cools down to make the joining permanent. Lead has a melting point of 327.46 degrees Celsius (621.43 degrees Fahrenheit) and therefore it can be used as solder. Mercury, however, has a melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit) and it is liquid even at room temperature. Therefore it cannot be used as solder because a liquid that does not solidify cannot be expected to join two surfaces permanently.

What is solder melting point?
Depends on the kind of solder.
What is the Melting temperature of lead solder?
homologous temperature
What is the lowest temperature that melts soft solder?
The melting point depends on the solder. The lowest I've seen is 395F.
Why does solder need to have a low melting point?
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
Is heating a chocolate chemical change?
Yes, burning of a sparkle is a chemical change because once sparkle has changed its form it cannot come into its previous form. For understanding you can also take the example of cooked rice which once cooked cannot be raw again.
How are the components inside the system unit connected?
With solder and hot-melting glue.
Why is the low melting point of solder an advantage when soldering?
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.
Solder is made of tin and lead but what is the other chemical?
Traditional electronics solder also contains resin.

What is a multicore solder?
Solder comes in 2 basic varieties, solid and rosin-core. Simple rosin-core solder is a tube of low-melting-point metal with flux filling the single core down the center. Multicore solder has multiple hollows in it, each filled with flux.
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.
