During soldering, a mixture of metals ('solder') is heated until it melts. The molten metal falls into the gaps between two piec
Pavlova-9 [17]

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
