2. Density: The density of tin is 7.3 g/cm³, making it denser than aluminum but still relatively lightweight.
3. Melting point: Tin has a melting point of 231.93 °C (449.47 °F).
4. Boiling point: The boiling point of tin is 2602 °C (4716 °F).

B. Chemical Properties

1. Reactivity with water: Tin is relatively unreactive with water, although it can be slowly oxidized by air.
2. Corrosion resistance: Tin is resistant to corrosion and is often used as a coating for other metals to protect them from corrosion.
3. Oxidation resistance: Tin is resistant to oxidation and can withstand exposure to air and moisture without rusting.
4. Electrical conductivity: Tin is a good conductor of electricity and is used in a variety of electrical applications.

The combination of its softness, corrosion resistance, and electrical conductivity make tin a valuable metal in industries such as food packaging, electronics, and coatings.

Differences Between Aluminum and Tin

There are several differences between aluminum and tin, including:

A. Physical Differences

1. Appearance: Aluminum is a silvery-white metal with a dull luster, while tin is a soft, silvery-white metal.
2. Density: Aluminum has a lower density of 2.7 g/cm³, while tin has a higher density of 7.3 g/cm³.
3. Melting point: Aluminum has a higher melting point of 660.32 °C (1220.58 °F), while tin has a lower melting point of 231.93 °C (449.47 °F).
4. Boiling point: Aluminum has a higher boiling point of 2467 °C (4472.6 °F), while tin has a higher boiling point of 2602 °C (4716 °F).

B. Chemical Differences

1. Reactivity with water: Aluminum is highly reactive with water, while tin is relatively unreactive.
2. Corrosion resistance: Aluminum has a high resistance to corrosion due to the formation of a thin, protective layer of aluminum oxide on its surface, while tin is often used as a coating to protect other metals from corrosion.
3. Oxidation resistance: Both metals are resistant to oxidation and can withstand exposure to air and moisture without rusting.
