During boiling the temperatre of the boiling liquid does not go up. The energy input into the boiling liquid is taken away as the latent heat of evaporation by the escaping gaseous phase.

What are three change of state in which energy is absorbed?
Energy is absorbed during melting, boiling and sublimation.
How can the temp of a substance remain the same if it is absorbing energy?
This happens during boiling and freezing the energy being absorbed is going into making the state change.
Is energy created during an exothermicreaction?
Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.
What are 2 processes for which thermal energy is required during boiling?
convection and radiation
During an energy change?
What changes and what remains the same during a physical change
What are three change of state in which energy is absorbed?
Energy is absorbed during melting, boiling and sublimation.
Is the boiling point of one liter of water different from the boiling of 2 liters of water?
No, boiling point is not affected by volume. What will change is the amount of energy you need to put in to get it to boiling point.
Does the amount of energy change during a chemical reaction?
duuh...of course it does
What states that during any change the amount of energy stays the same?
Law of Conservation of Energy.
What is the latent of vaporization?
The latent heat of vaporization is what is commonly referred to as boiling. This is the amount of energy require to change from a state of liquid to vapor.
How can the temp of a substance remain the same if it is absorbing energy?
This happens during boiling and freezing the energy being absorbed is going into making the state change.
How a change in energy can change into liquid water?
by boiling the water or putting it in the sun
Is energy created during an exothermicreaction?
Mass and energy can never be created or destroyed, but can change forms. An exothermic reaction releases stored chemical energy and transforms it into heat, but the total amount of energy does not change.
Does cooking change how much energy one get from foods?
Certain methods of cooking, boiling for example, can reduce the amount of nutrition available from a food.
How does the total amount of energy change as the energy is changed from potichal to kinetic?
The total amount of energy doesn't change in this case.
Why the temperature does not rise during the process of melting and boiling though the heat energy is constantly supplied?
The energy must be applied to the phase change before it can heat the substance
Why steam at 100 degree centigrade produces more severe burns then boiling water at 100 degree centigrade?
Steam has enough kinetic energy to leave the liquid water that is boiling, so it's greater amount of energy results in more severe burns than boiling water, which has a lower amount of energy.
