Which property of copper is used for chill strips?

• A. Electrical conductivity
• B. Thermal conductivity
• C. Electrical resistance
• D. Heat capacity

Answer: (B)

Chill strips work by pulling heat away from a hot surface, so the property that matters is how quickly a material can transfer heat. Copper’s high thermal conductivity means it can move heat away very fast, making it ideal for cooling applications like chill strips. Electrical conductivity and low electrical resistance describe how well copper conducts electricity, which isn’t the mechanism used for cooling. Heat capacity describes how much energy is needed to raise copper’s temperature, not how quickly it can remove heat. So the feature being relied on is copper’s ability to conduct heat efficiently.
