The image contains a series of problems related to physics and energy units, suitable for use on an educational website. --- ### Physics and Energy Unit Problems **5) The highest fuel costs in the world are in Norway (unsurprising since it is a major producer of oil). If $1 = 6.03950 kr (Norwegian Krone), and fuel costs in Norway are typically listed as 15.37 kr/L, what is the cost in $/gal?** Enter your answer in the box provided. **6) The units of heat capacity are:** A) KJ or °C/J B) J/K or J/°C C) J/g-K or J/g-°C D) J/mol E) g-KJ or g°C/J **7) 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 _______ joules in one Btu. 1 lb = 453.59 g; C = (5/9)(F-32); specific heat of H2O (l) = 4.184 J/g·K.** Select from: A) 3415 B) 6029 C) 10.54 D) 5.120 x 10^-3 **8) How many significant figures are there in each of the following measurements? Place your answer in the box.** --- For any graphs or diagrams, please ensure that you describe them in the context of the problems provided. They may include unit conversions, heat capacity measurements, and significant figure calculations. This problem set is designed to test students' understanding of unit conversions, heat capacity, the concept of British thermal units (Btu), and significant figures in measurement.
