Verified step by step guidance

1. Step 1: Understand the conversion factors needed for each part of the problem. For energy conversions, remember: 1 kWh = 3.6 × 10^6 J, 1 Cal = 4.184 kJ, and 1 cal = 4.184 J.
2. Step 2: For part a, convert 534 kWh to joules (J) using the conversion factor 1 kWh = 3.6 × 10^6 J. Multiply 534 kWh by 3.6 × 10^6 J/kWh.
3. Step 3: For part b, convert 215 kJ to Calories (Cal) using the conversion factor 1 Cal = 4.184 kJ. Divide 215 kJ by 4.184 kJ/Cal.
4. Step 4: For part c, convert 567 Cal to joules (J) using the conversion factor 1 Cal = 4.184 kJ. First, convert Calories to kilojoules by multiplying 567 Cal by 4.184 kJ/Cal, then convert kJ to J by multiplying by 1000 J/kJ.
5. Step 5: For part d, convert 2.85 × 10^3 J to calories (cal) using the conversion factor 1 cal = 4.184 J. Divide 2.85 × 10^3 J by 4.184 J/cal.
