How do you find the vapor pressure of water if the know temp of the water is 21 degrees C and the atmospheric pressure is 99.70 k Pa?

use the equation log P= 10.23 - (1750/ 21 + 235)

What is the boiling point of water in space?
The boiling point of a liquid is the temperature where the vapor pressure is equal to the atmospheric pressure. Vapor pressure increases with temperature, as you heat the water up the vapor pressure keeps increasing until it matches the atmospheric pressure, then it is boiling. Space isn't quite a perfect vacuum, so the boiling point wouldn't be 0, but it would be very very low.
How can a temperature in degrees Fahrenheit be below freezing if it is above 0 degrees F?
On the Fahrenheit scale, the freezing temperature of water is 32 degrees at atmospheric pressure. On the same scale, the freezing temperature of gold is 1,948 degrees at atmospheric pressure.
What is the boiling point of water at a higher altitidue than sea level?
Yes it does. Something boils when its vapor pressure equals the atmospheric pressure. The higher one goes the lower the pressure. If the pressure is lower then the water does not need as much vapor pressure in order to boil, and thus the temperature is lower.
What temperature does water evaporate and what temperature does water freeze?
in atmospheric pressure water evaporates at 100 degrees Celsius and freeze at 0 degrees Celsius. This may vary based on pressure
Why does a can that has boiling water get crushed when it is stuck in cold water in a sink?
A can containing a small amount of boiling water is filled with water vapor and very little or no air. When cooled quickly, the water vapor condenses into a few drops of water, leaving a partial vacuum in the can. Air cannot enter the can thru the small opening fast enough to equalize the internal pressure with the external atmospheric pressure, and it is crushed by atmospheric pressure.
Can you have water vapor at -10 degrees Celsius?
Yes. As long as the pressure is below atmospheric pressure.
Why rainwater evaporates when it is not 100 degrees Celsius?
Water evaporates at almost any temperature. However, at higher temperatures, the vapor pressure is higher. It is said to be boiling when the vapor pressure is equal to the atmospheric pressure.
What is the boiling point of liquids?
212 Degrees Fahrenheit,100 Degrees Celsius
What effect does increase water vapor have on atmospheric pressure?
it causes a decrease in atmosperic pressure A+
What is vapor pressure of water?
The vapor pressure of pure water at 25 degrees Celsius is 23.8 torr.
Which of the following can occur to water at 100 ºC?
Water at 100 degrees C, at standard atmospheric pressure, is right on the boundary between boiling into vapor and remaining as liquid water.
Why does water boil when the vapor pressure is equal to atmospheric pressure?
Because while atmospheric pressure is the greater of the two the vapour pressure of the water can not spontaneously form bubbles (ie boil).
Why does Atmospheric pressure exists because air has what?
Because air has water vapor.
Why does water boil at a lower temperature on a mountain than sea level?
The boiling of any liquid is tied in to the atmospheric pressure, in an open system. Every liquid has it's own vapor pressure, that is the balance between the vapor and liquid phase. When atmospheric pressure decreases, the vapor pressure increases since now there is greater space for the molecules of the liquid to come into vapor phase. At higher altitudes, the atmospheric pressure is lesser, that is, the air is thinner. Thus the liquid can attain higher vapor pressure faster and boil at a lower temperature.
What temperature does water turn into gas?
the point at which a liquid turns into a gas depends on the atmospheric pressure and the liquid water turns to gas at 100 degrees C at 1atm of pressure
What is the volume of 1 cu ft of water vapor at 1750 degrees F and atomspheric pressure when cooled to 100 degrees F?
Should this question be? = What is the volume of 1 cu ft of water vapor at 100 degrees F and atmospheric pressure? = It's initial volume doesn't matter as you only want to know what its final volume is.
What is atmospheric humidity?
Atmospheric humidity is defined as the amount of pressure of water vapor in an air to water mixture. This will be influenced by the temperature at a given time.
