It takes more energy to heat water from room temperature to 100 degrees Celsius than it does to bring it from 100 degrees Celsius to its boiling point, because the latter only involves phase change (from liquid to gas) without an increase in temperature. Once water reaches 100 degrees Celsius, additional energy input is needed to overcome intermolecular forces for boiling to occur.
At standard conditions, water will boil at 100 degrees Celsius.
The formula for water absorption coefficient is based on Lambert-Beer's Law and is expressed as: α = 2.303 / L * log(I0/I), where α is the absorption coefficient, L is the thickness of the material, I0 is the incident light intensity, and I is the transmitted light intensity.
The time it takes for water to start boiling depends on factors like the heat source, the amount of water, and the container. Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level, where the atmospheric pressure is around 1 atmosphere.
No machine can be 100% efficient because some energy is always lost to factors such as friction, heat, or sound during the conversion process. This energy loss results in the machine not being able to output as much useful work as the input energy provided.
If by "boil" you mean have it all evaporate, that takes MUCH more energy. For example, to increase the temperature of one gram of water from 20 to 100 degrees Celsius, you need 4.2 joules/gram/degree times 80 degrees = about 336 joules; then, to evaporate all the water, you need an additional 2257 joules.
In a house, usually 100 watts approx
100 mL × × × 40.65 kJ/mol = 226 kJ
Water evaporates at 100 so it would not be possible to boil an egg at 200
8.30 minutes

Salt water will boil at 108 degrees Celsius, so getting it to the boil will take 8% longer under the exact same circumstances as when you heat it to 100 degrees. How much time it will take in minutes depends on how high you will turn up the fire, if you will put a lid on the pan, whether you turn up or down the heat halfway etcetera.

The specific heat of water is 4,179 J/g.For a cup of 250 mL the energy is:250 x 4,179 x 100 = 104 475 J = 0,104 GJ.
Boiling tar typically takes around one to two hours, depending on the amount of tar being boiled and the intensity of the heat source.
It takes approximately 14.7 pounds per square inch (psi) at sea level to make water boil. This is equivalent to the atmospheric pressure at sea level.
