What is the unit of thermal conductivity ?
Correct answer: A. Kcal/hr.m.°C
- A. Kcal/hr.m.°C
- B. Kcal/hr. m2 °C
- C. Kcal/hr.m
- D. Kcal/hr. °C
Explanation
Thermal conductivity relates heat-transfer rate to area, temperature difference, and length, giving units of heat/(time × length × temperature). Therefore the listed unit is kcal/(hr·m·°C).
