Which one is colder 0 degrees Fahrenheit or200degrees kelvin?
200 Kelvin is colder - it is -99.67 F.
How does the size of one degree Celsius compare with that of one degree Fahrenheit and one degree Kelvin?
The size of the degree is the same in the Kelvin and Celsius scales.
What is the value of 1 kelvin?
Kelvin is the thermodynamic temperature (or absolute temperature) unit (S.I. unit). One kelvin temperature interval is equal to one Celsius degree interval. As interval, delta(T) = 1 K = 1oC. e.g., "cool down a body 12oC" is equivalent to "cool down a body 12 K". To find the equivalent Celsius temperature for a thermodynamic (or absolute) temperature in Kelvin, you have to recall that the "thermodynamic zero Kelvin temperature" ("absolute zero temperature") corresponds to -273.15oC. This and the one-one interval relation gives you the following relation: T(Kelvin) = T(Celsius degree) + 273.15 e.g., What is the equivalent absolute temperature in Kelvin for 20oC ? T(K) = 20oC + 273.15 = 293.15 K ≈ 293 K If you want to translate centigrade to Kelvin, from the previous relation you get: T(oC) = T(K) - 273.15 e.g., What is the equivalent Celsius temperature for 500 K ? T(oC) = 500 K - 273.15 = 226.85oC
Why is it important to convert it to kelvin or Celsius?
Kelvin is an absolute temperature, whereas both Celsius and Fahrenheit (as well as others) do not have an absolute zero value. The advantage of the Celsius scale is that one Celsius degree is the same as one degree on the Kelvin scale. As a result temperature changes are the same whether measured in Kelvin or degrees C. Besides, nobody apart from the US uses Fahrenheit anyway. Oh, yes, also Burma and Liberia.
One degree Celsius indicates the same temperature change as what in Fahrenheit and Kelvin?
The size of a "degree" on the Kelvin scale is identical to the size of a Celsius degree. So a change (up or down) of 1°C is the same as a change of 1 Kelvin. The size of a Fahrenheit degree is much smaller. A change of 1°C (up or down) is the same as a change of 1.8° on the Fahrenheit scale. Example : 10° C = 283.15 K = 50° F 11° C = 284.15 K = 51.8° F
