The British thermal unit (Btu)is commonly used in engineering applications. A Btu is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 °F. There are ________ Btu in one Joule. 1 lb = 453.59 g; °C = (5/9)(°F - 32°); specific heat of H₂O (l)= 4.184 J/g-K. A)1056 Btu B)1.896 × 10^-3 Btu C)9.278 × 10^-4 Btu D)5.120 × 10^-3Btu E)Additional information is needed to complete the calculation.

To convert Btu to Joules, use the specific heat formula: 1 Btu = 1 lb × 1 °F × 4.184 J/g-K × 453.59 g/lb × (5/9) K/°F = 1055.06 J. Therefore, 1 Joule = 1/1055.06 Btu ≈ 9.478 × 10^-4 Btu.
