When the vapor pressure of water is 30 kPa the temperature of water is?
When the vapor pressure of water is 30 kPa the temperature of water is?
700C.
Answer: The temperature of the water when the vapour pressure is 30 kPa is 700C.
What is the vapor pressure of water at 50 C?
92.5
Vapor Pressure of Water from 0 °C to 100 °C
| T °C | P (torr) |
|---|---|
| 47 | 79.6 |
| 48 | 83.7 |
| 49 | 88.0 |
| 50 | 92.5 |
When the vapor pressure is 101.3 kPa What is the temperature of water?
100 °C
For a liquid to boil the pressure of gas above the liquid must equal the vapor pressure and bubbles will form in the liquid. Hence water boils at 100 °C when the pressure is 1 atm (101.3 kPa).
What is the vapor pressure of water at 70 C in kPa?
30 kPa
It hits the axis at 70 °C. Thus, the vapour pressure of water is 30 kPa at 70 °C.
What is vapour pressure of liquid Class 12?
Vapour Pressure of a Liquid Vapour pressure is the pressure exerted by vapours when they are in equilibrium with the liquid phase at a given temperature. It depends on the nature of the liquid and temperature. Vapour pressure of pure liquid is always greater than the vapour pressure of its solution.
What is the boiling point of water at 50 kPa?
Example- Lowering the atmospheric pressure to 50kPa, will change waters boiling point to about 78oC.
How do you find vapor pressure of water?
Simple formula simple_pressure = e^(20.386 – (5132 / (temperature + 273)) , where vapor pressure is expressed in mmHg and temperature in kelvins.
What is the vapor pressure of water at 25 C?
The vapor pressure of water at room temperature (25° C) is 0.0313 atm, or 23.8 mm of mercury (760 mm Hg = 1 atm).
What is the vapor pressure of ethanol at 50 C?

What is the vapor pressure of water at 23.5 C?
| Water vapor pressure in mm Hg between 15.0°C and 30.8°C | ||
|---|---|---|
| Temperature (°C) | 0.0 | 0.8 |
| 23 | 21.068 | 22.110 |

| 25 | 23.756 | 24.912 |
What is the vapor pressure of water at high pressure?
At higher pressures water would condense. The water vapour pressure is the partial pressure of water vapour in any gas mixture in equilibrium with solid or liquid water. As for other substances, water vapour pressure is a function of temperature and can be determined with the Clausius–Clapeyron relation. Vapour pressure of water (0–100 °C)
How do you calculate vapor pressure from temperature?
In our calculator you’ll find implemented: simple_pressure = e^(20.386 – (5132 / (temperature + 273)), where vapor pressure is expressed in mmHg and temperature in kelvins. The temperature T is expressed in degrees Celsius and the vapor pressure P is in mmHg.
What is the Most Accurate KPA formula for temperature?
The most often used is the Antoine equation (4.232 kPa), but the Buck formula (4.245 kPa) is usually the most accurate one for temperature ranges we typically look for. If you want to get the result in different pressure unit, simply click on the unit name and choose the one you need: Pa, hPa, torrs, mmHg or any other unit.
What is the difference between temperature (OC) and pressure (kPa)?
Temperature (oC) Pressure (mm Hg) Pressure (kPa) Temperature (oC) Pressure (kPa) 0.0 4.6 0.61 23.0 2.81 5.0 6.5 0.87 23.5 2.90 10.0 9.2 1.23 24.0 2.98 15.0 12.8 1.71 24.5 3.10
