Which of the following statements is true about metals?

The statement indicating that most metals are solid at room temperature and conduct heat well is accurate because it reflects the general physical properties associated with metals. Most metals, like iron, copper, and aluminum, remain solid at room temperature, with very few exceptions such as mercury, which is a liquid metal.

Moreover, metals are known for their excellent thermal conductivity. This property allows them to transfer heat efficiently, which is why metals are commonly used in cookware and heat exchangers. Their ability to conduct heat is closely related to their metallic bonding structure, which allows electrons to move freely throughout the material.

This understanding aligns well with what is known about the properties of metals, making this statement the correct choice. Other provided statements do not accurately summarize common characteristics of metals.
