What is the temperature at which the rate of evaporation equals the rate of condensation?
The temperature at which the rate of evaporation equals the rate of condensation is known as the equilibrium vapor pressure. At this temperature, the vapor pressure of a liquid is equal to the external pressure, leading to a dynamic equilibrium between the liquid and vapor phases.
Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Why do vapor bubbles not form in water at room temperature and standard pressure?
we know that water bubbles are formed when external pressure becomes equal to the internal pressure so room temperature is 20 digree to 25 digree and internal pressure deos not equal to external pressure at this temperature so it is clear that vapor bubbles deos not formed in water at room temperature and standard pressure where standard pressure is 760 torr.
What is the point at which a liquids vapor pressure equals the atmospheric pressure?
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
When the vapor pressure of a liquid equals the air pressure in the room what will the liquid do?
When the vapor pressure of the liquid equals the air pressure in the room, the liquid will reach equilibrium and stop evaporating. This is because the rate of evaporation is equal to the rate of condensation.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point

The temperature at which the vapor pressure of a liquid has an external pressure of 1 ATM is the?
The vapor pressure of a liquid is equal to 1 atmosphere at 100 degrees Celsius, or 212 degrees Fahrenheit. This is because for a liquid to boil, its vapor pressure must rise to reach standard atmospheric pressure, which is about 1 atmosphere. When enough heat is present to do this, the substance will boil.
The temperature at which the vapor pressure of a liquid is equal to the exernal pressure is the?
It's called the triple point. For example when an ice-skater is skating, the thin blade creates a lot of pressure over a small area. So where the skate contacts the ice, you have solid (ice), liquid, and small amount of water vapor.
What is difference between critical temperature and boiling point?
The critical temperature is the highest temperature at which a substance can exist in a distinct liquid and gas phase, above which the substance becomes a supercritical fluid. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure, causing the liquid to transition into a gas phase.
Liquid boiling point?
boiling point of a liquid is directly related with the external pressure(some times Air pressure). directly related means that increase in value of one variable(independent) results in increasing value of other variable(dependent). when the vapor pressure of the liquid becomes equal to that of external pressure,the liquid boils. The temperature at which they becomes equal is called Boiling piont of liquid.
When does boiling point occur?
For water it is 100 degrees celsius, however it is different for other liquids ------------------------- Generally, boiling point is the temperature at which the liquid's vapour pressure is equal to the external atmospheric pressure.
What term defines the temperature at which the vapor pressure of the liquid equals the atmospheric pressure?
The temperature at which the vapor pressure of the liquid equals the atmospheric pressure is called THE BOILING POINT.
Under the same heating conditions same power element same volume etc can water be heated to 100 degree's C faster at 2 bar pressure than at 1 bar or does it take the same time?
It takes the same time. However, at a pressure of 2 bar (higher pressure), the water will not boil at 100oC. This is because boiling occurs at that temperature for which the saturated vapour pressure of the liquid is equal to external pressure. Since the external pressure has been increased, a higher temperature is required to make the vapour pressure of the liquid become equal to the external pressure. Hence, the boiling point increases.
What happens at a liquid's boiling point?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it.
