Key Points

• Temperature in Kelvin can never be negative (statement iii) and can be zero or a positive definite quantity (statement iv).
• The Kelvin scale starts at absolute zero (0 K = −273.15°C), the theoretical lowest temperature where all molecular motion stops.
• Unlike Celsius or Fahrenheit, Kelvin has no negative values.
