Question

Which of the following metals has the lowest melting point?

• A. Aluminium
• B. Tin
• C. Zinc
• D. Copper

Hint:

Metals with low melting points like tin and lead have historically been easy to work with and are common in solders and low-temperature casting alloys.

Answer 1

The Correct Option is B

Step 1: Determine the approximate melting points of the metals.

Copper (Cu): ~1085°C (1984°F)
Aluminium (Al): ~660°C (1220°F)
Zinc (Zn): ~420°C (787°F)
Tin (Sn): ~232°C (450°F)

Step 2: Analyze the values.Tin has the lowest melting point, approximately 232°C. This makes it suitable for solders and alloys like pewter.
