I do not understand how they went from [itex]\ln T_c-\lnT_H=\theta_c-\theta_H[/itex]
to
[itex]\theta=\ln T+C[/itex]
Why did the subscripts drop out? What just happened?
The Kelvin scale is a temperature scale that starts at absolute zero (-273.15 degrees Celsius) and is based on the properties of ideal gas laws. It is commonly used in scientific research and is the standard unit for temperature in the International System of Units (SI).
Unlike the Celsius and Fahrenheit scales, which are based on arbitrary values, the Kelvin scale is based on absolute zero. This means that the Kelvin scale has no negative values and it is the only temperature scale that does not use the degree symbol.
The formula for converting degrees Celsius to Kelvin is K = °C + 273.15. This is because the Kelvin scale starts at absolute zero, which is equivalent to -273.15 degrees Celsius.
To convert degrees Fahrenheit to Kelvin, you can use the formula K = (°F + 459.67) x 5/9. This is because the relationship between the Fahrenheit and Kelvin scales is based on the same interval, but the zero points are different.
The last step in converting temperature to Kelvin is to add 273.15 to the temperature in degrees Celsius. This is because the Kelvin scale starts at absolute zero, which is equivalent to -273.15 degrees Celsius. By adding 273.15, you are essentially shifting the temperature to the Kelvin scale, where 0 is equivalent to absolute zero.
