Which of the following temperatures represents the lowest value?

• A. 0 °C
• B. 0 °F
• C. 0 K
• D. 100 K

Answer: (C)

Verified step by step guidance

1. Understand the temperature scales involved: Celsius (°C), Fahrenheit (°F), and Kelvin (K). Each scale has a different zero point and unit size.
2. Recall the conversion formulas between these scales. For example, to convert Celsius to Kelvin: \(K = C + 273.15\).
3. Convert 0 °C to Kelvin using the formula: \(0\,^{\circ}C = 0 + 273.15 = 273.15\,K\).
4. Convert 0 °F to Kelvin by first converting Fahrenheit to Celsius using \(C = \frac{5}{9}(F - 32)\), then convert Celsius to Kelvin.
5. Compare all temperatures in the same unit (Kelvin) to determine which is the lowest value.
