Temperature to which air must be cooled to reach saturation?
The temperature to which air must be cooled to reach saturation is called the dew point.
Which term refers to the temperature to which air would have to be cooled to reach saturation?
It is the Dew point.
What happens to volume when air temperature increases?
If pressure remains constant, then volume is directly proportional to temperature. Hot air is quite loud.
A gas originally at 27C and 1.0atm pressure in a 3.9 L flask is cooled at constant pressure until the temperature is 11C What is the new volume of gas?
3.7 L
What does saturation have to do with dew point?
The dew point is a saturation point, but a saturation point may not be a dew point. That is, a saturation point has a broader definition -- more general application. Sometimes you can interchange the terms without confusing the reader. =================================
How much relative humidity would decrease when temperature rises?
Relative humidity is a ratio between the partial pressure of water vapor and the saturation pressure of water vapor at the current temperature and pressure. If the temperature and pressure change, then the relative humidity will change also. You are correct that higher temperatures allow the atmosphere to hold more water. That means that the saturation pressure of water vapor has increased while the current vapor pressure has remained the same, causing the relative humidity to drop. We think of humidity as how hot and sticky it is outside. The closer the water vapor pressure is to its saturation point, the more hot and sticky we feel. We associate humidity with heat since that is when we are uncomfortable, but rain is caused by the relative humidity rising to 100% because the humid air cooled to the point that the saturation pressure dipped below the current vapor pressure (or other pressure changes, or a combination of both). You can learn more at the link below. I hope this helps.
What is the volume of the gas before and after cooled?
The volume of a gas - at constant pressure - is proportional to the absolute temperature, that is, to the temperature expressed in Kelvin. This relationship is only approximate for real gases, but it is close enough for most practical purposes.
What is sub-cooled liquid?
LIQUID COOLER THAN THE CONDENSING SATURATION TEMPERATURE (125 degree Fahrenheit ) IS CALLED SUBCOOLED LIQUID
A sample of Xenon gas at 20degree Celsius and 0.570 ATM is cooled to a pressure of 0.100 ATM If the volume remains constant What is the final Celsius temperature?
It would be -221.7 deg C.
Why is the dew point never the same?
The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.The dew point is associated with relative humidity. A high relative-humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decreaseTherefore, by the above stated reasons (of humidity and barometric pressure and saturation based on temperature) are all reasons the point at wick dew forms is not the same because the regions them selves vary and thus these relative factors maybe dissimilar.
Why does temperature affect the air pressure?
Air temperature and air pressure are inversely proportional. As temperature increases, air pressure decreases. This is best demonstrated in an enclosed vessel.
A gas is measured at room temperature 24 deg C and is found to have a pressure of 100.0 kPa What is the new pressure if the gas is cooled to standard temperature O K?
LESS
