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 water reaches its boiling point, it undergoes a phase change from liquid to vapor. At this point, any additional heat applied to the water will not raise its temperature further, but rather increase the rate of vaporization. Therefore, applying more heat on boiling water is a waste of energy as it will not significantly affect the temperature or any other properties of the water.

How a machine transforms energy into waste energy?
A machine transforms energy into waste energy in that the motor is moving fast and the waste energy is produced.
What is waste thermal energy?
Waste thermal energy refers to thermal energy caused by friction. It usually a waste product that results when energy changes form or performs work.
What w is energy that is not useful?
Waste energy.
What is the difference between force and conservation of energy?
Force implies that you waste energy while in conservation you do not waste it.
Why does heat energy become waste energy?
When it is not captured

When is waste-to-energy thermoelectrics coming out?
Check the Wikipedia article on "waste-to-energy" - it looks as if such plants already exist.

What is waste-to-energy?
waste to energy (wte) is the process of creating energy in the form of electricity or heat from waste sources.
Does geothermal energy leave waste?
No, geothermal energy has no waste.
How can we make nuclear energy cleaner?
Nuclear Energy is already clean. The problem is the 'radio-active' waste from the reactor. A lot of research is going on to dispose of radio-active waste safely. One possibility is 'vitrifiction' and then burying it in deep mines.
When you do not waste energy you do what to energy?
The word "conserve" basically means "not waste" (or "not use").
What is waste thermal energy?
Waste thermal energy refers to thermal energy caused by friction. It usually a waste product that results when energy changes form or performs work.
What we energy that is not useful?
Waste energy
What effect does the waste energy from a transformer have on the air around the?
Waste energy is converted to heat.
What is waste to energy conversion?
Waste to Energy Conversion is when you take waste (the combustible parts of household garbage, for example, that cannot be otherwise recycled) and burn it to run an electricity generator. Then you have used waste to make energy.
