Facts
- The Kelvin scale is named after Lord Kelvin (William Thomson), a British physicist.
- Kelvin is the SI base unit of temperature, used widely in science.
- Absolute zero (0 K = -273.15°C) is the lowest possible temperature.
- A change of 1 K is the same as a change of 1°C.
- The Kelvin scale does not use the degree symbol (°).
Frequently Asked Questions
0°C equals 273.15 K. This is the freezing point of water at standard atmospheric pressure. To convert, simply add 273.15 to the Celsius value.
No, Kelvin cannot be negative. The Kelvin scale starts at absolute zero (0 K = -273.15°C), which is the lowest physically possible temperature where all molecular motion ceases.
Kelvin is the SI base unit of temperature and starts at absolute zero, making it an absolute scale. This is essential for scientific calculations like gas laws, thermodynamics, and radiation physics where ratios of temperatures must be meaningful.
Absolute zero is 0 K (-273.15°C or -459.67°F), the theoretical lowest temperature. At this point, particles have minimal vibrational motion. It has never been fully achieved in a laboratory, though scientists have come within billionths of a degree.
Room temperature is approximately 293-298 K, which corresponds to 20-25°C (68-77°F). In scientific contexts, standard temperature is often defined as exactly 298.15 K (25°C).
