Which term describes the ability to transfer heat or electricity between objects?

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

Answer: (A)

Conductivity describes how readily energy can pass between objects, whether as heat or electricity. If a material has high electrical conductivity, electric current moves through it easily (think copper wires). For heat, high thermal conductivity means heat flows quickly from hot to cold areas (metals transfer heat well). The other terms relate to different concepts: life-cycle analysis looks at environmental impact over a product’s life, ripple effect refers to indirect consequences, and ecodesign is about designing products to minimize environmental impact. Because conductivity directly captures the ability to transfer energy as heat or electricity, it is the best fit.
