Provide the value below in K:
The Kelvin (K) is the SI unit of temperature used in scientific contexts to measure absolute temperature. It is named after the physicist William Thomson, Lord Kelvin. The Kelvin scale starts at absolute zero, the theoretical point where molecular motion ceases, and increments are equivalent to those on the Celsius scale. Kelvin is crucial in scientific research and engineering, particularly in fields like thermodynamics and quantum mechanics, where absolute temperature measurements are essential.
The Rankine (°R) scale is an absolute temperature scale used primarily in thermodynamics and engineering in the United States. It is similar to the Kelvin scale but uses Fahrenheit degrees for increments. The Rankine scale starts at absolute zero, just like Kelvin, but with 1 Rankine degree being equivalent to 1 Fahrenheit degree. It is used to analyze thermodynamic processes in systems where temperature measurements are relative to absolute zero, often in the context of heat engines and refrigeration.
To convert a temperature from Kelvin (K) to Rankine (°R), we use the formula:
Rankine = Kelvin × 1.8
Let's go through the conversion step by step for 20 K:
Therefore, 20 Kelvin is equivalent to 36 Rankine.
