Answer :
The melting point and the normal boiling point of water in respective temperatures in kelvins are 273 and 373. The correct option is 5.
What is the boiling point?
The boiling point is the point of water when the water vapor of the water is equal to the water vapor of the atmosphere.
The melting point is the point when a solid-state converts into liquid, and changes its physical state.
In Celsius, the boiling point is 100⁰C
In Kelvin, 273 + 100 = 373 K
The melting point is ice is 0⁰C
273 + 0 = 273 K
Thus, the correct option is 5. 273 and 373.
