During soldering, a mixture of metals ('solder') is heated until it melts. The molten metal falls into the gaps between two piec

es of metal and freezes, joining the pieces of metal together. A 'soft solder' melts between 183 °C and 212 °C. A 'hard solder' melts between 620 °C and 680 °C. Explain the difference in melting ranges.

Answer:

$31^oC$

Explanation:

Range = Highest value - Lowest value

A 'soft solder' melts between 183 °C and 212 °C.

Melting range of a 'soft solder' = $212-183=29^oC$

A 'hard solder' melts between 620 °C and 680 °C.

Melting range of a 'hard solder' = $680-620=60^oC$

So,

Difference in melting ranges = Melting range of a 'hard solder' - Melting range of a 'soft solder' = $60^oC-29^oC=31^oC$
