The lower fixed point of an graduated thermometers 20-degree office much is 100 calculate the equivalent reading in Kelvin scale thermometer?
To calculate the equivalent reading in Kelvin scale, we need to convert from the Celsius scale to the Kelvin scale.
The Kelvin scale starts at absolute zero, which is equivalent to -273.15 degrees Celsius. On the Celsius scale, the lower fixed point is 0 degrees.
To convert from Celsius to Kelvin, we use the formula:
Kelvin = Celsius + 273.15
In this case, the lower fixed point on the Celsius scale is 20 degrees. So, to find the equivalent reading in Kelvin, we can use the formula:
Kelvin = 20 + 273.15
Calculating,
Kelvin = 293.15
Therefore, the equivalent reading on the Kelvin scale for a 20-degree Celsius temperature is 293.15 Kelvin.
