I hope this helps you please mark as brainliest answer.......

Explanation:

A good source will say when you heat something up, energy is used for two things:

Increase kinetic energy of particles.

Break (intermolecular) bonds.

Kinetic energy means the speed of the particles. Temperature is a measure of this (and only this). So temperature = speed of the particles.

Going back, we said energy go into two things. That is a bit of a simplification:

The thing is, intermolecular bonds break because of kinetic energy. Just before a bond is broken, the kinetic energy of the liquid particles involved the bond are momentarily is higher. The bond then breaks, absorbing some of the kinetic energy, leaving the particles slower than before.

At boiling point, the energy of your average liquid particle is so high that it is barely able to keep any intermolecular bonds.

At boiling point, any energy input will still momentarily increase the kinetic energy of the particles. The particles then immediately break any intermolecular bonds that they have left and turn into gas phase. At boiling point, increasing the particle speed while keeping some bonds around is no longer possible. Hence, the particle speed remains constant (temperature remains constant) while bonds keep breaking.

Answer:

plz Mark me as brainlist ☺️☺️☺️☺️☺️

Explanation:

When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. ... In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling
