Question

which temperature scale is kelvin? (with an image showing temperature scales labeled a, b, c and multiple - choice options a, b, c)

Explanation:

Step1: Recall Kelvin scale properties

Kelvin scale starts at absolute zero (0 K), and the freezing point of water is 273.15 K, boiling point is 373.15 K. Celsius scale: freezing 0°C, boiling 100°C. Fahrenheit: freezing 32°F, boiling 212°F.

Step2: Analyze the scales

Looking at the options, the Kelvin scale (C) should have values like 273 K (freezing) and 373 K (boiling), matching the scale where values are higher (since K = °C + 273.15). So the correct one is C.

Answer:

C
