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 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.
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.
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.
When the vaper pressure of a liquid is equal the atmosphere pressure is?
When the vapor pressure of a liquid equals the atmospheric pressure, the liquid reaches its boiling point. At this temperature, the liquid molecules have enough energy to overcome intermolecular forces and transition into the vapor phase. This phenomenon allows the liquid to rapidly convert to gas, resulting in boiling. The boiling point varies with changes in atmospheric pressure; for instance, it decreases at higher altitudes where atmospheric pressure is lower.
What is the pressure of the sample of gas trapped in the open-tube mercury manometer shown below if atmospheric pressure is 736 mmHg and h equals 9.2 cm?
The pressure of the gas is equal to the atmospheric pressure plus the difference in the heights of the mercury levels. To convert 736 mmHg to cm, divide by 1.333. Then calculate the difference in heights: 9.2 cm. Add the two values together to find the pressure of the gas.
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.
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.
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.
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.
Number of inches of mercury when pressure equals 68 millibars?
68 millibars = 2.008 inches of mercury.
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.
