Question

Give reason the temperature of water remains constant during boiling​

Answer 1

Answer:

In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling. For example, water will remain at 100ºC (at a pressure of 1 atm or 101.3 kPa) while boiling.

Answer 2

$\huge\boxed{Answer}$

The temperature remains constant during boiling of water even though heat is supplied constantly because all the heat energy provided is used up in changing the state of water from liquid to gaseous water vapour. Therefore all the heat energy provided to the liquid  increases the kinetic energy of the particles and temperature doesn't increase. So supplied heat energy is used to increase kinetic energy of molecules.
