To convert a temperature from Celsius to Kelvin, you simply need to add 273.15 to the Celsius temperature.
In this case, the boiling point of alcohol is given as 70 degrees Celsius.
To convert it to the Kelvin scale, you would perform the following calculation:
70 degrees Celsius + 273.15 = 343.15 Kelvin
Therefore, the boiling point of alcohol, which is 70 degrees Celsius in Celsius, is equivalent to 343.15 Kelvin on the Kelvin scale.
