1 BTU/lb.←°F is equivalent to ____________ kcal/kg.°C?
Correct answer: A. 1
- A. 1
- B. 2.42
- C. 1.987
- D. 4.97
Explanation
Including the Fahrenheit-to-Celsius interval conversion, 1 Btu/(lb·°F) equals approximately 4.187 kJ/(kg·K). Since 1 kcal/(kg·°C) is also 4.187 kJ/(kg·K), the equivalent value is 1.
