The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
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.
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.
Vapor pressure is measured when a liquid and its vapor are?
in a state of dynamic equilibrium at a constant temperature. At this point, the rate of vaporization equals the rate of condensation, resulting in a constant pressure above the liquid known as the vapor pressure.
Why does lowering pressure cause a liquid to boil?
it becomes easier for the molecules to escape
What is the meaning of boiling in science terms?
Actually boiling is a point where the vapour pressure of any liquid (example: water) becomes equal to the surrounding pressure.
How is vapor pressure related to the boiling point?
Vapor pressure is related to the boiling point because the boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. When the vapor pressure of a liquid reaches the same pressure as the surrounding atmosphere, the liquid will boil and turn into a gas.
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.
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.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
What is the temperature where the vapor pressure of a liquid equals atmospheric pressure?
The boiling point of the liquid.
When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
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 the liquid boils when its vapor pressure becomes equal to ATM pressure?
When the vapor pressure of a liquid equals the atmospheric pressure, the liquid molecules are escaping the liquid surface as quickly as they are returning, causing the liquid to boil. This is because the vapor pressure represents the point at which the liquid and gas phases are in equilibrium and the liquid can transition to a gas phase.
What two factors determine the point at which a liquid will boil?
Heat or energy applied and atmosphereic pressuresPressure and temperature (apex)
When should the boiling point of a liquid be recorded?
The boiling point of a liquid should be recorded when the liquid reaches a constant temperature at which it changes from a liquid to a gas (vapor) under a specific pressure. This usually occurs when the vapor pressure of the liquid equals the atmospheric pressure.
The reduced vapor pressure at high altitudes causes a liquid to boil at a?
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
