Which term describes the ability of an object to transfer heat or electricity to another object?

• A. Conductivity
• B. Electrical conductivity
• C. Life-cycle analysis
• D. Ripple effect

Answer: (A)

The concept tested is how readily energy moves through a material. This property is called conductivity, describing how easily energy can transfer as heat or as electricity. When energy moves easily as heat, the material has high thermal conductivity; when it moves easily as electricity, it has high electrical conductivity. Because the question mentions both heat and electricity, the general term conductivity is the best fit. Electrical conductivity would only cover electricity and miss the heat aspect. Life-cycle analysis relates to environmental impact over a product’s life, not energy transfer, and a ripple effect refers to indirect consequences, not a physical property.
