Which property is defined as the ability to conduct heat or electric current?

• A. Hardness
• B. Conductivity
• C. Elasticity
• D. Ductility

Answer: (B)

Conductivity is the property that describes how easily heat or electric current can move through a material. It captures how well a substance can transmit energy—high electrical conductivity means electrons flow readily, while high thermal conductivity means heat passes through quickly. Materials like copper exemplify high electrical conductivity, making them excellent for wiring; metals also typically have good thermal conductivity, helping heat spread. In contrast, hardness measures resistance to scratching or denting, elasticity describes how well a material returns to its original shape after deformation, and ductility refers to how much it can be drawn into a wire. Understanding conductivity helps you choose materials for applications where energy transfer is desired (high conductivity) or minimized (low conductivity).
