What is the relationship of boiling point with atmospheric pressure?
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
Where does boiling take place in a liquid?
Boiling occur in the entire volume of the liquid.
What equals the force of Earth's atmosphere on the mercury in the dish?
The force of Earth's atmosphere on the mercury in the dish is equal to the atmospheric pressure acting on the surface area of the mercury. This can be calculated using the formula ( F = P \times A ), where ( F ) is the force, ( P ) is the atmospheric pressure (approximately 101,325 Pa at sea level), and ( A ) is the surface area of the mercury in the dish. The pressure exerted by the atmosphere pushes down on the mercury, causing it to rise in a connected column, such as in a barometer.
When vaporization takes place on and below the surface of liquid at higher temperature the pricess is called?
The process you are describing is called boiling. Boiling occurs when the vapor pressure of a liquid equals the atmospheric pressure, causing bubbles of vapor to form within the liquid.
Why doeswater's boiling point decrease with increase in elevation?
Water's boiling point decreases with an increase in elevation because the atmospheric pressure decreases at higher elevations. Water boils when its vapor pressure equals the atmospheric pressure. As atmospheric pressure decreases with elevation, the vapor pressure required to boil water also decreases, resulting in a lower boiling point.
Why do balloons expand as they rise through the troposphere?
The ballon contains a fixed amount of gas producing internal pressure. At the surface, this pressure equals the surface atmospheric pressure. As the balloon rises, the atmospheric pressure drops, allowing the balloon to expand, keeping the internal pressure and external pressure equal. If the balloon is fully inflated at the surface it will burst at higher altitude.
Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
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.
What happens at a substance's boiling point?
Its vapor pressure equals atmospheric pressure.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
The conversation of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
What is the temperature where the vapor pressure of a liquid equals atmospheric pressure?
The boiling point of the liquid.
One ATM equals standard ATMospheric pressure at sea level Choose the correct measure of one ATM?
Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
When vapor pressure equals atomospheric pressure what is the liquid?
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
At what point, in terms of vapor pressure, will a liquid boil?
A liquid will boil when its vapor pressure equals the atmospheric pressure.
What depth equals 100 bar?
If you mean in the ocean, approximately every 10 meters pressure increases by 1 bar. Assuming you want absolute pressure, at the surface you already have a pressure of approximately 1 bar - the atmospheric pressure. You can base your calculations on that.
What is the relationship between pressure and the boiling points of liquid?
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.
