Because heat changes the temperature of the water
The amount of heat needed to boil water varies with the air pressure. Water in a vacuum will boil at room temperature.

To boil water successfully, place a pot of water on the stove over high heat. Wait for the water to come to a rolling boil, where bubbles are rapidly rising to the surface and breaking. Once boiling, reduce the heat to maintain a gentle boil as needed for your recipe.
No, you cannot boil water using a magnifying glass. A magnifying glass can only concentrate sunlight to create heat, but it is not powerful enough to generate the high temperatures needed to boil water.
The heat required to boil water can be calculated by multiplying the mass of water (21.1 g) by the specific heat capacity of water (4.18 J/g°C) and the temperature change (100°C - initial temperature). This calculation results in 8.82 kJ or 8820 J of energy needed to boil 21.1 g of water at 100°C.
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
To properly boil water in a pan, fill the pan with water, place it on a stove over high heat, and wait for the water to come to a rolling boil. Once it reaches a boil, reduce the heat to maintain a gentle boil until the water is ready for use.
The material that will boil water the fastest is metal. Metal is an excellent conductor of heat and will heat the water up quickly.
No, water that is covered does not boil faster. Covering the pot can actually trap heat and make the water boil slower.
No, you cannot boil water with dish soap. Dish soap is not a heating element and does not generate heat to boil water.
Extreme heat...boil the water.
No, infrared light can generate heat, but typically not enough to boil water on its own. It usually requires direct contact with a heat source, like a stove or fire, to bring water to a boil.
