The physical state of copper is solid at room temperature. Copper is a metal that is known for its high thermal and electrical conductivity. It is commonly found in electrical wires, plumbing pipes, and various industrial applications. In its solid state, copper has a characteristic reddish-orange color and a metallic luster. It is a malleable and ductile material, which means it can be easily shaped and drawn into wires. This property makes copper suitable for applications that require flexible and conductive materials. Copper also has a relatively high melting point of 1,085 degrees Celsius (1,984 degrees Fahrenheit), which means it requires a significant amount of heat to change its physical state from solid to liquid. This property makes copper suitable for high- temperature applications such as electrical components and heat exchangers. Overall, the physical state of copper is solid, and its properties make it a valuable material in various industries.
