Can you compare vapor pressure of water at ten degrees Celsius with its vapor pressure at fifty degrees Celsius?
The vapor pressure of water at 10°C is lower than at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase. At 50°C, the water molecules are more energetic and escape into the air more readily compared to at 10°C.
Compare the vapor pressure of water at 10 C with its vapor pressure at 50 C?
Vapor pressure of water at 10 0C is less than that at 50 0C because, like gas pressure, as temperature rises, the kinetic energy of particles increases, thus increasing pressure. So the pressure of water vapor at 50 0C has more vapor pressure than at 10 0C.
How many grams of sucrose must be added to 500 g of water at 100 celsius to change the vapor pressure to 755 mm Hg?
To change the vapor pressure of water to 755 mm Hg at 100°C, you would need to add sucrose to create a solution with a lower vapor pressure than pure water. The amount of sucrose needed to achieve this specific vapor pressure depends on the molal concentration of the sucrose solution and its van't Hoff factor. To calculate this accurately, you would need additional information about the sucrose-water system.
What causes cool temperatures of water vapor?
Cool temperatures of water vapor are usually caused by the expansion of the vapor, leading to a decrease in temperature through adiabatic cooling. This can occur when water vapor rises in the atmosphere, expands due to lower pressure, and cools as it ascends. Additionally, the mixing of cooler air with warm, moisture-laden air can also cause the temperature of water vapor to decrease.
If you had a cubic meter of air at 20 degrees C that was holding 3 grams of water what would the relative humidity be?
To calculate the relative humidity, we need the actual vapor pressure (partial pressure) of water in the air and the saturated vapor pressure at the air temperature. At 20 degrees C, the saturated vapor pressure of water is around 2.34 kPa. By converting 3 grams of water to moles and calculating its partial pressure, we can find the relative humidity is approximately 46.2%.

What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
The vapor pressure of water at 10°C is lower than its vapor pressure at 50°C. As temperature increases, the vapor pressure of water also increases because more water molecules have enough energy to escape into the gas phase.
How does vapor pressure of water at 50 oC compare with its vapor pressure at 50 oC?
The saturated vapor pressure of water at 50 oC is 123,39 mm Hg.
How does the vapor pressure of water at 10 degrees celsius with its vapor pressure at 50 degrees celsius?
Do you mean, how does the pressure of water vapor at 10˚C compare with its pressure at 50˚C?The vapor pressure of water is the pressure at which steam is saturated. Above this pressure, the water would begin to condense. In a gas mixture saturated with water vapor, the vapor pressure is equal to the partial pressure. The vapor pressure is a function of temperature. Many equations of state can predict vapor pressures of liquids but the best ones are also rather complex and require considerable expertise to use. For most purposes, there are several simpler empirical equations which can estimate the vapor pressures of liquids with sufficient accuracy for most purposes.One of the simplest is the Antoine equation which has the form:log10Pvap = A - B/(C+T) where the Pressure (P) is in mmHg and the Temperature (T) is in °C.For water in the range from 1 °C to 100 °C, the constants have the values:A = 8.07131B = 1730.63C = 233.426Using these values, the vapor pressure of water can be estimated as:Pvap(@10 °C) = 9.158817 mmHgPvap(@50 °C) = 92.29989 mmHg... so the vapor pressure of water at 50 °C is roughly 10 times the vapor pressure at 10 °C.
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
At 117°C, the vapor pressure of water is approximately 2566 Pa.
What is the vapor pressure of water at 21.5C?
The vapor pressure of water at 21.5°C is approximately 19.8 mmHg. This value represents the pressure exerted by water vapor when in equilibrium with liquid water at that temperature.
Why does water in the rivers not evaporate at 100 C?
I will be astonished if you show me a river at 100 degrees Celsius in which the water is not actually boiling, let alone evaporating. Perhaps you mean: why does water in rivers evaporate at temperatures below 100 degrees Celsius. To which the answer is: water has a finite vapor pressure at every temperature; if that vapor pressure exceeds the partial pressure of water vapor in the atmosphere above the water, some of the water will evaporate until the partial pressure is equal to the vapor pressure. Even ice evaporates. Make some ice and leave it in your freezer for a long time. The ice cubes will shrink.
What is the normal boiling point of the chloroform which has a higher vapor pressure than water at 100 Celsius is?
The normal boiling point of chloroform is approximately 61.2°C. Since chloroform has a higher vapor pressure than water at 100°C, it means chloroform will boil first before water at that temperature, due to its lower boiling point.
