1. An inventor claims to have developed a food freezer that at steady state requires a power input of 0.6 kW to extract energy by heat transfer at a rate of 3000 J/s from freezer contents at 270 K. Evaluate this claim for an ambient temperature of 293 K.
2. An inventor claims to have developed a refrigerator that at steady state requires a net power input of 0.7 horsepower to remove 12,000 Btu/h of energy by heat transfer from the freezer compartment at 08F and discharge energy by heat transfer to a kitchen at 708F. Evaluate this claim.
