Question

which of the following thermometers have absolute zero? options: fahrenheit (red), celsius (blue), rankine (orange), kelvin (green)

Explanation:

• Fahrenheit: Its zero point is based on arbitrary definitions (freezing of a brine solution), not absolute zero.
• Celsius: Zero is the freezing point of water, not absolute zero.
• Rankine: It is an absolute temperature scale (based on Fahrenheit), so it has absolute zero (0 Rankine is absolute zero).
• Kelvin: It is an absolute temperature scale where 0 K is defined as absolute zero (the theoretical temperature where all molecular motion stops).

Answer:

C. Rankine, D. Kelvin
