Question

The boiling point of water on Celsius and Kelvin scale respectively is:
a) 373, 273
b) 0, 273
c) 273, 373
d) 100, 373
​

Answer 1

c) 273, 373

the two reference temperatures for Celsius, the freezing point of water (0°C), and the boiling point of water (100°C), correspond to 273.15°K and 373.15°K, respectively.

Answer 2

The boiling point of water on the Celsius and Kelvin scales respectively is 100°C and 373K.

• The boiling point of water is defined as the temperature at which water starts boiling.
• On the Celcius scale, the boiling point of water is 100°C.
• We know that 0°C is equal to 273K.
• Hence 100°C is equal to 273+100=373K.
• So, the boiling point of water in kelvin is 373K.
• Hence the correct option is d.
