What is the density of PURE water in its liquid state?
At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.
Asume benzene insoluble in water the normal boiling point of benzene and water is 80.1'c and 100'c respectively at a pressure of 1 ATM what will be the boiling point of mixture of benzene and water?
The partial pressures of water and benzene will be their corresponding vapor pressures at the boiling point so it must add up to 1 atm and this happens at roughly about 342-343 K.
What is the osmotic pressure of 18.6 grams of a solute with molecular mass of 8940 grams are dissolved in enough water to make 1000 mL of solution at 25 C?
.49 ATM
The temperature inside a pressure cooker is 117 C Calculate the vapor pressure of water inside the pressure cooker?
2.90
Can you boil the water at 95 C and 105 C if the ordinary water boils at its boiling point?
Yes: the boiling point depends on the pressure.
What temp does water freeze at partial vacuum?
The freezing point of water decreases as the pressure decreases in a partial vacuum. At standard atmospheric pressure (1 atm), water freezes at 0°C (32°F). However, at reduced pressures, water can remain in a liquid state at temperatures below 0°C due to the lower pressure affecting its freezing point.
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.
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 state of OXYGEN at 25 degrees C?
Pure oxygen is a gas at 25 C, regardless of the pressure.
What will be state of water at -25 C?
At -25 Celsius, water will be a solid. Converting from Celsius to Fahrenheit, -25 C is -13 F.
What is the pKa of glucose?
12.28 at 25°C 12.28 at 25°C in water
Partial pressure of oxygen in Mexico City?
It is of approximately 21.15 KPa at 17 °C (77% rel. humidity)
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.
What will be the state oh water at 25 C?
The state of water at -25 C is solid. Water freezes at 0 degrees Celsius.
What is the density of PURE water in its liquid state?
At 25 degrees C the density of water is 1.0 g/mL. If the temperature of the water goes above 25 degrees C the density will drop. If the temperature of the water goes below 25 degrees C the density will rise.
Asume benzene insoluble in water the normal boiling point of benzene and water is 80.1'c and 100'c respectively at a pressure of 1 ATM what will be the boiling point of mixture of benzene and water?
The partial pressures of water and benzene will be their corresponding vapor pressures at the boiling point so it must add up to 1 atm and this happens at roughly about 342-343 K.
Does the pressure is affected if is difference liquids?
Yes. Pressure of a liquid could be considered in two ways. 1. The subsurface pressures. 1 ATM is the pressure of our atmosphere on earth which is equivalent to a pressure of 14.7 PSI. This is the same pressure as would be exerted by 34 feet of water. So, if one dives to 34 feet, one would actually feel 2 ATM of pressure or 29.4 PSI TOTAL. However, this is the same pressure as is developed by 760mm (or 30 inches) of mercury. So a diver would feel the same 2ATM (29.4 PSI TOTAL) in less than 3 feet of Mercury. 2. Partial Pressures & Vapor Pressures. The partial pressures and vapor pressures are dependent on the type of liquid and the temperature. When the partial pressures or vapor pressures reach 1 ATM, the substance boils. So, for example, the vapor pressure of Methanol at 64.7 °C, 148.4 °F is 1 ATM, and thus it will boil. However the vapor pressure of pure water at the same pressure is significantly less than 1 ATM, and the water does not boil. This is used to distill substances. However, as with water/alcohol mixes, the water does exert a certain vapor partial pressure on the mix and one typically gets a mixture with a significant fraction of water in the final product.
