Can you boil a liquid without changing temperature?
Water boils under normal atmospheric pressure at 212°F (100°C). … For another example, put water at room temperature into a vacuum chamber and begin removing the air. Eventually, the boiling temperature will fall below the water temperature and boiling will begin without heating.
What is the best way to boil water?
High heat is useful when you want to get the water to reach boiling temperature quickly. Once you’ve got where you want, reduce the heat to medium (for boiling) or medium-low (for simmering). Once the water is at a rolling boil, more heat will only make it boil away faster.

What happens when water boils?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
What happen to the temperature of water while it is boiling?
Temperature of a substance during its phase change remains constant. Hence when water boils, the temperature of water remains constant i.e 100oC.
What is the most economical way to boil water?
An electric teakettle is about 80 percent efficient, although again this varies from kettle to kettle. Electric kettles are generally very well insulated, and the heating coils sit directly in the water, so less heat is lost to the air. An induction stove or hot plate is about 85 percent efficient.
