Why is it a waste of energy to apply more heat on water that is already boiling?
Any such heat will convert water to vapor; the water's temperature won't increase, and any such heat will usually serve no useful purpose. Only a small amount of heat is required to keep water boiling - enough to compensate for heat losses.
When a kettle boils what are the energy transfers?
When a kettle boils, energy is transferred from the electric heating element to the water in the form of heat. The heat energy causes the water to increase in temperature until it reaches its boiling point, at which point some of the heat energy is also used to convert the water into steam.
Why do you need heat to boil water?
Boiling water requires heat to increase the temperature of the water molecules, causing them to gain enough energy to overcome the intermolecular forces holding them together in the liquid state. This results in the water reaching its boiling point and transforming into vapor.
How does boiling water affect the temperature of a room?
Boiling water can increase the temperature of a room by releasing heat energy into the surrounding air. This can lead to a temporary rise in room temperature until the water cools down.
What energy does boiling water use?
Boiling water typically uses thermal energy, which is the energy associated with heat. When water reaches its boiling point, the thermal energy added to the water causes the water molecules to gain enough kinetic energy to break free from their liquid state and change into vapor.

What can you do to increase the temperature of boiling water?
To increase the temperature of boiling water, you can apply more heat to the water by turning up the stove or using a higher heat setting. You can also increase the pressure around the water, which will lead to a higher boiling point.

What heat energy do you feel from boiling water?
A lot.
What contains more heat energy?
A cup of boiling water contains more heat energy than a cup of lukewarm water because the boiling water is at a significantly higher temperature. Heat energy is directly related to the temperature of an object.
How would the measured value of specific heat be affected if some boiling water were carried over with the sample?
If boiling water were carried over with the sample, it would increase the measured value of the specific heat. The excess heat energy from the boiling water would contribute to raising the overall temperature of the sample, leading to a higher specific heat value being calculated.
How can boiling water be used to generate heat efficiently?
Boiling water can be used to generate heat efficiently by transferring the heat energy from the boiling water to a heating system, such as a radiator or a steam turbine. The high temperature of the boiling water allows for a significant amount of heat energy to be produced, which can then be used to warm up a space or generate electricity.
