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 the vapor pressure of water at 10 degrees celsius compare with its vapor pressure at 50 degrees celsius?
The vapor pressure of water at 10 degrees Celsius is lower than at 50 degrees Celsius. As temperature increases, so does the vapor pressure of water because more water molecules have enough energy to escape into the gas phase.
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.
How does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
The vapor pressure of water at 50ºC will be greater than that at 10ºC because of the added energy and thus greater movement of the water molecules. If one knows the ∆Hvap at a given temperature, one can calculate the vapor pressure at another temperature. This uses the Clausius-Clapeyron (sp?) equation. It turns out the vapor pressure of water at 10º is 9.2 mm Hg, and that at 50º is 92.5 mm Hg.
What is the approximate vapor pressure when the liquid water boils at about 50 C?
The approximate vapor pressure of water at 50°C is around 92.5 mmHg.

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 does the vapor pressure of water at 10C compare with its vapor pressure at 50C?
The vapor pressure of water at 50°C is significantly higher than at 10°C. As temperature increases, the kinetic energy of water molecules also increases, allowing more molecules to escape into the vapor phase. Consequently, the vapor pressure, which is the pressure exerted by the vapor in equilibrium with its liquid, rises with temperature. Therefore, at 50°C, the vapor pressure of water is much greater than at 10°C.
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.

What compound has the lowest vapor pressure at 50 degrees celsius?
At 50 degrees Celsius, a compound with the lowest vapor pressure would be one with strong intermolecular forces like hydrogen bonding, such as water (H2O). These strong forces make it harder for molecules to escape into the gas phase, resulting in a lower vapor pressure compared to compounds with weaker intermolecular forces.
What does relative humidity measure?
Relative Humidity is actually measure the amount of moisture in the air. It depends on how much of the air has water in it. Let's say that the RH is 50%, that means 50% of the air has water in it.
A parcel of air is at 20 and has a saturation vapor pressure at 24 mb If the water vapor content actually exerts a vapor pressure of only 12mb in 20 air the relative is What would the ap?
To calculate the relative humidity, you can use the formula: [ \text{Relative Humidity} = \left( \frac{\text{Actual Vapor Pressure}}{\text{Saturation Vapor Pressure}} \right) \times 100 ] In this case, the actual vapor pressure is 12 mb, and the saturation vapor pressure is 24 mb. Thus, the relative humidity is: [ \text{Relative Humidity} = \left( \frac{12 \text{ mb}}{24 \text{ mb}} \right) \times 100 = 50% ] Therefore, the relative humidity of the air parcel is 50%.
If a 5050 mixture of cyclohexane-toluene is boiled what will the relative ratios of the vapor be?
AnswerDetermine the bp of clycohexane and that of toluene. The lower bp chemical will come off first. A simple distillation rig will provide a means of monitoring when the first chemical has been removed. The remaining chemical will likely have some amount of the first remaining, depending upon distillation rig used.The more complicated answer is that the ratios of vapor will change over time as the solution boils.When the solution is boiling the total vapor pressure of the solution is equal to atmospheric pressure. That total vapor pressure is the sum of the two partial pressures of toluene and cyclohexane (the components). So what your asking is what is the partial pressure of each; then you can compare them to make a ratio. Well, the partial pressure of each component in the vapor is the vapor pressure of that component at the current temperature of the system times the mole fraction of that component in the liquid.Toluene has a lower vapor pressure than cyclohexane (it is less volatile) so if you start with a 50/50 mixture of cyclohexane and toluene (50/50 by mole fraction, that is, but 50/50 by volume is pretty close), the partial pressure of toluene is (lower number)x50% and the partial pressure of cyclohexane is (higher number)x50%, so there's more cyclohexane in the vapor than there is toluene. However...Those vapors tend to float away and leave the system. Since there's initially more cyclohexane in the vapor, more cyclohexane is leaving the system and you no longer have a 50/50 mixture. Eventually it gets to the point where the partial pressure of toluene is (lower number)x(larger fraction) and the partial pressure of cyclohexane is (higher number)x(smaller fraction) so there is actually more toluene in the vapor.
