Question

The boiling point o of ethyl alcohol is 78°c.What is the corresponding temperature on kelvin scale?

Answer 1

351.15K is the answer because we just have to add 273.15 to 78 to get answer :)

Answer 2

351 K is the Kelvin scale temperature of the ethyl alcohol.

Solution:

Boiling point of the given alcohol = 78°C

Kelvin scale temperature = Celsius scale temperature + 273

Kelvin scale Temperature = 78 + 273

= 351 K

Hence, temperature of 78°C on Celsius scale is equal to 351 K on the Kelvin scale.

Kelvin scale of temperature is invented by “Lord William Thomson Kelvin”. It is used only for research work by the scientist. For measuring temperature, Kelvin is the SI unit. K is the symbol used for representing Kelvin. Kelvin scale and Celsius scale of temperature has a relationship and is written as,

Temperature on Kelvin scale = Temperature on Celsius scale + 273
