Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
What is boiling short answer?
Boiling is the process by which a liquid turns into a vapor when it is heated to its boilingpoint. The change from a liquid phase to a gaseous phase occurs when the vapor pressure of the liquid is equal to the atmospheric pressure exerted on the liquid.
What is the meaning of boiling for kids?
Kids Definition of boil (Entry 2 of 3) 1 : to heat or become heated to the temperature at which bubbles form and rise to the top boil water. 2 : to cook or become cooked in boiling water boil eggs Let the stew boil slowly. 3 : to feel angry or upset The crowd boiled in frustration.
What is boiling in science?
In science, boiling happens when liquid becomes gas, forming bubbles inside the liquid volume. In cooking, water is the most frequently used liquid that is boiled. The temperature when water will begin to boil is around 212 degrees Fahrenheit/100 degrees Celsius. This is called the boiling point.
What is the best definition of boiling?
The process of changing the state of a substance from liquid to gas by heating it to its boiling point.
What do you mean by boiling?
From Wikipedia, the free encyclopedia. Boiling is the rapid vaporization of a liquid, which occurs when a liquid is heated to its boiling point, the temperature at which the vapour pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding atmosphere.
How does boiling work?
When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. … In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling.
What does boil mean in cooking?
boiling, the cooking of food by immersion in water that has been heated to near its boiling point (212 °F [100 °C] at sea level; at higher altitudes water boils at lower temperatures, the decrease in boiling temperature being approximately one degree Celsius for each 1,000 feet [300 metres]).
What is melting and boiling?
melting point is the temperature at which a solid changes into a liquid. boiling point is the temperature at which a liquid changes into a gas.
What is boiling point of water?
A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.
What is boiling and example?
A good example of boiling is seen when water is heated until it forms steam. The boiling point of fresh water at sea level is 212°F (100°C). The bubbles that form in the water contain the vapor phase of water, which is steam.
What is boiling point in physics?
boiling point, temperature at which the pressure exerted by the surroundings upon a liquid is equaled by the pressure exerted by the vapour of the liquid; under this condition, addition of heat results in the transformation of the liquid into its vapour without raising the temperature. Fast Facts.
What is the definition of boiling point in chemistry?
Boiling point is the temperature at which a liquid changes to a gas (vapor) at normal atmospheric pressure. A more specific definition of boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure.
What word class is boiled?
Verbs are action words and state of being words.
What is boiling and evaporation?
Boiling, evaporation and condensation are terms that refer to the changes in state between liquids and gases: Boiling occurs when a liquid is heated and turns to a gas. Evaporation occurs when a liquid changes to a gas at a temperature below its normal boiling point.
What is boiling in home economics?
The expected answer: Boiling is a method of cooking food in water which is at a temperature of 100°C with the water covering the food. … – Boiling is an economical method of cooking/cheap method of cooking. – Easy method of cooking. – Stock may be used. (c) State two disadvantages of boiling as a method of cooking.
