Question

What are the units of absolute zero in Fahrenheit, Celsius, and Kelvin?

1) Fahrenheit, Celsius, and Kelvin
2) Fahrenheit, Celsius, and Rankine
3) Fahrenheit, Kelvin, and Rankine
4) Celsius, Kelvin, and Rankine

Answer 1

Absolute zero is -459.67°F, -273.15°C, and 0 K on the Fahrenheit, Celsius, and Kelvin scales, respectively. The Kelvin scale is the SI unit and does not use a degree sign. Temperature differences are the same in units of kelvins and degrees Celsius.

Step-by-step explanation:

The units of absolute zero on the Fahrenheit, Celsius, and Kelvin temperature scales are important in understanding the concept of the lowest theoretically possible temperature. The correct units for expressing absolute zero across these scales are as follows:

• Fahrenheit: -459.67°F
• Celsius: -273.15°C
• Kelvin: 0 K

The Kelvin scale is the SI unit of temperature and is an absolute temperature scale with 0 K representing absolute zero. Unlike Celsius and Fahrenheit, the Kelvin scale does not use a degree sign because it is an absolute scale. The freezing and boiling points of water on the Kelvin scale are 273.15 K and 373.15 K, respectively, which corresponds to 0°C and 100°C on the Celsius scale. The relationship between Celsius and Kelvin scales is direct; thus, temperature differences are the same in both units, where ΔTC = ΔTK.
