Question

The boiling point of alcohol is $ {78^0}C $ , what is the temperature on kelvin scale?

Answer 1

Hint: Temperature is the amount of heat contained in any object and was measured by a device known as a thermometer. This thermometer measures the temperature in different scales like Celsius, kelvin, and Fahrenheit. Conversion can be made from one scale to another scale.

Complete Step By Step Answer:
Chemical compounds are classified into functional groups based on the groups present in it. Some of the functional groups are alcohols, esters, ethers, carboxylic acids and so on.
Alcohols are the chemical compounds consisting of the $ - OH $ group. Alcohol mostly has a high boiling point due to the ability of formation of hydrogen bonding.
Given that the boiling point of alcohol is $ {78^0}C $ .
From the above statement, it was clearly expressed that the temperature is expressed in Celsius scale. Temperature is defined as the intensity or degree of heat present in a substance. The temperature can be expressed by thermometer in different scales or different units.
The different scales include Celsius, kelvin, and Fahrenheit. When the temperature can be expressed in Celsius, it can be converted into kelvin by adding $ 273 $ .
As $ {1^0}C = 273K $
The given boiling point can be written as $ {78^0}C = 78 + 273 = 351K $
Thus, when the boiling point of alcohol is $ {78^0}C $ , the temperature on kelvin scale will be $ 351K $ .

Note:
For so many chemical conversions or processes like ideal gas law, the units of temperature must be in kelvin. The standard unit of temperature is kelvin. When the temperature is given in Celsius or Fahrenheit, conversion should be made and then only, it should be used.
