A temperature of 41 degrees F is equivalent to 278.2 degrees K, while a temperature of 86 degrees F is equivalent to 303.2 degrees K. Find the equation converting Kelvin temperature to Fahrenheit. What is the Fahrenheit temperature when it is 180 degrees K?
on converting fahrenheit to celsius then to kelvin.
C=(F-32)*(5/9)
K=C+ 273.15
How are they getting the answer 273.15?
To convert Celsius to Kelvin, you need to add 273.15 to the Celsius temperature. The value of 273.15 is derived from the specific calculation of the Kelvin scale. The Kelvin scale starts at absolute zero, which is the lowest temperature possible. Absolute zero is defined as 0 Kelvin, and it is equivalent to -273.15 degrees Celsius.
So, to convert from Celsius to Kelvin, you add 273.15 to the Celsius temperature. This ensures that temperatures below absolute zero are represented as negative values on the Kelvin scale.
For example, let's say you have a temperature of 100 degrees Celsius. To convert it to Kelvin, you would add 273.15:
K = C + 273.15
K = 100 + 273.15
K = 373.15
Therefore, a temperature of 100 degrees Celsius is equivalent to 373.15 Kelvin.
In the given equation, K = C + 273.15, it is used to convert temperature from Celsius to Kelvin.
