Questions & Step-by-Step Solutions

At what temperature does the Kelvin scale start?
  • Step 1: Understand what the Kelvin scale is. It is a temperature scale used in science.
  • Step 2: Know that the Kelvin scale starts at a point called absolute zero.
  • Step 3: Remember that absolute zero is defined as 0 Kelvin (0 K).
  • Step 4: Convert 0 K to Celsius to understand its value in another scale. It is -273.15°C.
  • Step 5: Conclude that the Kelvin scale starts at 0 K or -273.15°C.
  • Temperature Scales – Understanding the different temperature scales, particularly the Kelvin scale and its relation to absolute zero.
  • Absolute Zero – Knowledge of absolute zero as the theoretical lowest temperature, where molecular motion stops.
