Humidity is the amount of water vapor in the air at a given time. At warm temperatures, air can hold more moisture than it can at cold temperatures. Relative humidity is the amount of vapor the air is holding expressed as a percentage of the amount the air is capable of holding. For example, at 86 degrees Fahrenheit, air can hold a maximum of 30.4 grams of water per cubic meter. If the air at the same temperature is holding...
1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...
(a) What is the vapor pressure of water at 20.0◦C? (b) What percentage of atmospheric pressure does this correspond to? (c) What percent of 20.0◦C air is water vapor if it has 100% relative humidity? (The density of dry air at 20.0◦C is 1.20 kg/m3). I got that the vapor pressure of the water will be 2.33x103 Pa, but I am getting hung up on the formula for part b, which is where I can really use the extra help...
We are learning about relative humidity. 1st part- what is the water vapor content at 25 degree C air if its relative humidity is 50%? 50=10/20 x 100% gives me the water vapor content of 10g/kg. 2nd part- If the air was at 25 degree C at sea level, and rises to 1,000 meters, then what will its temperature be? It will drop by 10 degree C, so the temperature will be 15 degrees C. At 15 degree's C the...
A solution is made by mixing 41.0 mL of ethanol, C2H6O, and 59.0 mL of water. Assuming ideal behavior, what is the vapor pressure of the solution at 20 °C? Values at 20 C: ethanol, density = 0.789 g/mL, VP = 43.9 torr water, density = 0.998 g/ml, VP = 17.5 torr

"Vapor Pressure of Water" assignment:
VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
Hello need help with some practice questions.
thanks!
7. What is the advantage of repelling water from a leaf surface? 8. What is the saturated water vapor versus temperature curve and how can it be used to compute transpiration when air relative humidity and leaf/air temperature are known? 9. How is transpiration be computed according to the Ohm's Law analogy for electrical circuits?
