The boiling point is defined as the temperature that the liquid spontaneously turns into a vapour throughout the liquid. This is dependent on atmospheric pressure as the higher the pressure the more energy is required to produce the gas /vapour bubbles in the liquid. We see this effect when water boils and the surface is disturbed by the bubbles rising to the surface - it is boiling.
Water boils at a little over 60 oC (140 oF) at the top of Mount Everest but at 100 oC (212 oF) at sea level ie 1 ATM pressure. When water is boiled at a higher location than sea level it will boil at less than 100 oC depending on atmospheric conditions.
What else can I help you with?
Why is boiling called a bulk phenomenon?
Boiling occur in the entire volume of a liquid.
How does vaporization relate to evaporation and boiling.?
Vaporization occur at the boiling point and from the total volume of the liquid.Evaporation occur at any temperature but only from the surface of the liquid.
What is different evaporation and vaporization?
Evaporation occur at the surface of a liquid and at any temperature under the boiling point.Vaporization occur only at the boiling point and in the entire volume of the liquid.
What is liquid to gas evaporation called?
1. When the phenomenon occur at a temperature under the boiling point, at the surface of a liquid, the term is evaporation.2. When the phenomenon occur at the boiling point, in all the volume of the liquid, the term is boiling.
Why is it important to state the pressure at which boiling points occur?
It is important because boiling points are dependent onthe pressure.
What is the temperature for boiling water to start evaporating?
Evaporation occur at any temperature.Boiling occur at 100 oC.
When water boils it evaporates?
Evaporation occur at any temperature, boiling only at the boiling point - 100 oC at standard pressure.
Does evaporation or boiling occur more quickly?
Boiling occurs more quickly than evaporation. Boiling is the rapid vaporization of a liquid when it is heated to its boiling point, whereas evaporation is the slower process of a liquid turning into a gas at temperatures below its boiling point.
What temperature does boiling water get to when it starts to evaporate?
Evaporation occur at any temperature.
Where gas change occur at the?
The gas is transformed in a liquid under the boiling point.
Why is boiling dependent on pressure?
Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.
What is considered boiling water and at what temperature does it occur?
Boiling water is when water reaches a temperature of 212 degrees Fahrenheit (100 degrees Celsius) at sea level.
