The process that occurs during boiling of liquid is energizing of water molecules (H2O) to give them excessive energy for excitement to change their form to gas from liquid. This energy can be provided by heating and electric current.
In the liquid state, atoms and molecules are bound together by strong intermolecular forces as compared to gases.While boiling a liquid we provide heat to the molecules whereby their kinetic energy is enhanced and they now have enough energy to overcome the cohesive forces and escape from the liquid surface hence changing into gas.This process is called evaporation.

∙ 12y agoAn object (such as a stove top), transfers energy in the form of heat to the layer of liquid just above it through conduction. Convection then forces the heated liquid to rise, thereby heating more of the liquid and forcing the cooler liquid to replace it at the bottom. These convective currents are responsible for the roiling action found in a boiling substance.

Why does the temperature of a substance remain constant during it's melting point on boiling point?
Because of phase transition ie from solid to liquid during melting and from liquid to vapour during boiling. So just to change over from one phase to the other heat is totally utilized and hence no chance to have a rise in temperature. So temperature remains constant.
What happens to temperature during a phase change?
Temperature is constant during a phase change.
How do changes in air temperature affect water in the liquid and gas states?
If you leave water alone, it is in liquid form. If you raise the temperature of water to boiling, it creates steam. Is this a gas? If you lower the temperature to freezing, it becomes a solid.
Is the temperature remains constant when water starts boiling?
During boiling the temprature remains constant and as soon as the water is bolied the temprature again rises.
When does Boiling temperature Start?
The Boiling Point Temperature is 212 degrees Fahrenheit and 100 degrees Celsius
Which change takes place during the boiling water?
During boiling of water,water changes its state from liquid to gas due to a change in temperature. Therefore it is a physical change.
Can boiling temperature of an element change?
The boiling temperature of an element can change by changing the pressure.
Why is a baked potato chemical change?
At a high temperature (during boiling or frying) the composition of potatoes is modified - a chemical change.
What can you notice about the temperature of sea water during boiling?
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
What is boiling point in science?
during boiling,the temperature of a mixture is different at different times. during boiling,the temperature of a substance changes at the start then it becomes the same and constant.
How does the temperature of water change if you heat it after its has reached the boiling point?
it does not change
How does the temperature of water change if you heat it after it has reached the boiling point?
it does not change
When liquid is boiling its temp doesnt change?
At the boiling point the temperature remain unchanged.
Did the temperature change while the water was boiling?
Yes
Why does temperature remain constant during melting and boiling?
because of phase transtion i.e. from solid to liquid during melting and from liquid to vapour during boiling. so just to change over from one phase to the other heat is totally utilized.
How does temperature of water change if you heat it after it has already reached its boiling point?
it does not change
How does the water temperature of water change if you heat it after it has reached its boiling point?
it does not change
