In this article, we will explore the physical properties of copper and determine which statement accurately describes one of its characteristics.

Physical Properties of Copper

Copper is a chemical element with the symbol Cu and atomic number 29. It is a ductile, malleable, and highly conductive metal. Some of its notable physical properties include:

High Electrical Conductivity: Copper has an excellent ability to conduct electricity, making it a popular choice for electrical wiring and circuits.
High Thermal Conductivity: Copper is an excellent heat conductor, which makes it useful in applications where heat transfer is crucial.
Ductility: Copper can be drawn into thin wires or sheets without breaking, making it a versatile material for various applications.
Malleability: Copper can be pounded into thin sheets or foils without breaking, making it a popular choice for architectural applications.

Analyzing the Statements

Now that we have a basic understanding of copper's physical properties, let's analyze the given statements:

A. It reacts with strong acids.

Copper is a metal that can react with certain acids, but this reaction is not a physical property. When copper reacts with strong acids, such as sulfuric acid or hydrochloric acid, it forms a copper salt and releases hydrogen gas. This reaction is a chemical property of copper.

B. It can be reshaped by a force.

This statement accurately describes a physical property of copper. Copper is a ductile metal that can be reshaped by applying a force. This property makes it possible to draw copper into thin wires or sheets without breaking.

C. It ignites at high temperatures.

Copper does not ignite at high temperatures. While copper can melt at a relatively low temperature (around 1085°C), it does not ignite or burn like some other metals. This statement is not a physical property of copper.

D. It can combine with oxygen.

Copper can react with oxygen to form copper oxide, but this reaction is not a physical property. When copper reacts with oxygen, it forms a layer of copper oxide on its surface, which can affect its electrical conductivity and other properties.

Conclusion

In conclusion, the statement that describes a physical property of copper is:

B. It can be reshaped by a force.

This statement accurately describes copper's ductility, which is a physical property of the metal. Copper's ability to be reshaped by a force makes it a versatile material for various applications.
