What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
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.
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.
What is the approximate vapor pressure when the liquid water boils at about 50 C?
230 mm Hg
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.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
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.
Can you compare vapor pressure of water at ten degrees Celsius with its vapor pressure at fifty degrees Celsius?
Yes, the vapour pressure of water at 10°C is 1.2 kPa and at 50°C is 12.3 kPa.

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.
If the boiling points of two compounds differ by fifty degrees c at atmospheric pressure what would be the effect of dropping the pressure to ten mm?
Any time you drop the external temperature, it is going to make it easier for compounds to boil since the atmosphere is no longer exerting as much force down on the liquid. However, whether one or both compounds boils at that temperature depends less on the difference between their two boiling points and more on what their vapor pressure is at whatever temperature they are at. Compounds boil when their vapor pressure (the pressure of the molecules that naturally escape the solid or liquid because they have more energy) is the same as the external pressure. The vapor pressure of a substance depends only on temperature, which is why the point at which something boils is tied to temperature. Take water for instance. Water boils at 100 degrees C at sea level because at that temperature its vapor pressure is 1 ATM (760 mm Hg). At room temperature (25 degrees C) water has a vapor pressure of around 22 mm Hg. Since its vapor pressure at 25 degrees C exceeds 10 mm Hg, it would indeed boil at that pressure. Now if a liquid had a boiling point that was 50 degrees below water's, it would presumably boil at that temperature as well (although not necessarily... depends on other factors). If a liquid had a boiling point that was 50 degrees higher than water, then there is a decent chance it may not boil, but you would really need info on its vapor pressure at room temperature to know.
House water pressure?
House water pressure should be around 50-60 psi.
What does water pressure mean?
Water pressure refers to the pressure of water in a system. In a home it will be 30-50 psi typically and this is governed by the municipal pressure or by a well tank.
