Pronunciation: [bˈɔ͡ɪlz ɐwˈe͡ɪ] (IPA) 
The phrase "boils away" is spelled as /bɔɪlz əˈweɪ/. The "o" in "boils" is pronounced like the "oi" sound in "coin," and the "s" is pronounced like a "z" sound. The "a" in "away" is pronounced like the "ay" sound in "day." The phrase means that a liquid is heated to the point where it evaporates completely. It can be used in cooking or chemistry to describe the process of removing a liquid from a mixture through boiling.
"Boils away" is a phrasal verb used to describe the process of a liquid reaching its boiling point and subsequently converting into gas, often due to the application of heat. When a substance boils away, it undergoes a transformation from its liquid state into vapor or gas, causing it to gradually evaporate or disappear entirely.
This term is commonly associated with water, as it boils at 100 degrees Celsius (212 degrees Fahrenheit) at normal atmospheric pressure. As heat is added, the water molecules gain energy and become more energetic, causing them to move faster. When the thermal energy exceeds the cohesive forces between the water molecules, bubbles form and rapidly rise to the surface. These bubbles burst and release water vapor into the air, resulting in the eventual boiling away of the liquid.
The process of boiling away is not restricted to water alone but can be applied to any liquid reaching its boiling point. The rate at which the liquid boils away depends on various factors such as the heating temperature, surface area exposed to the heat source, atmospheric pressure, and the volatility of the substance.
In summary, "boils away" refers to the evaporation or transformative process in which a liquid rises in temperature to its boiling point, resulting in the conversion of the liquid to vapor or gas, causing it to gradually disappear or evaporate.
The term "boils away" is a combination of two words: "boils" and "away".1. Boils: The word "boil" derives from the Middle English word "boillen", which is a fusion of the Old English word "bȳlian" and the Old Norse word "býla". Both of these ancestral terms mean "to bubble, to seethe, or to be agitated". "Boil" refers to the process of bringing a liquid to its boiling point, causing it to heat up and produce bubbles and steam.2. Away: The word "away" traces back to the Old English word "āweg", which is comprised of "ā" (meaning "on", "in", or "to") and "weg" (meaning "way" or "path"). "Away" signifies movement from one place or position to another, implying a sense of separation or departure.
