Question

why temperature remain constant during boiling​

Answer 1

Answer:

TEMPERATURE remains constant during boiling because the heat absorbed at the boiling point is used to break the molecular bonds and make them loose to change their state. This is also latent heat of vaporization

Answer 2

Explanation:

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 increases the kinetic energy of the particles and temperature doesn’t increase. Once the water starts boiling, all the heat supplied will be used in the conversion of water into steam at the boiling point of water.
