What is the initial pressure of H2S gas in the flask with a Kp value of 0.120 at 25 deg C?
To determine the initial pressure of H2S gas in the flask, we need the total pressure and the partial pressure of another gas in equilibrium with H2S. Without the partial pressure of the other gas, we can't determine the initial pressure of H2S with just the Kp value and temperature provided.
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 phase is water in at 75 C and 9atm?
Water is in the liquid phase at 75°C and 9 atm pressure. At this temperature and pressure, water exists as a liquid due to the combination of temperature and pressure conditions present.
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.
What is water at 0 c and above 1 ATM pressure?
Water at 0°C and above 1 ATM pressure is in its liquid state. At this temperature, it is at the freezing point, but since the pressure is above 1 ATM, it does not freeze and remains liquid. This is due to the fact that water can exist as a liquid between 0°C and 100°C under normal atmospheric pressure. Thus, at 0°C and higher pressure, it will not transition to ice, but rather stay in its liquid form.
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 temp does water freeze at partial vacuum?
The freezing point of water decreases as the pressure decreases in a vacuum. At very low pressures, water can freeze at temperatures below 0°C due to reduced atmospheric pressure. The exact temperature at which water will freeze in a partial vacuum depends on the level of vacuum present.
What is the initial pressure of H2S gas in the flask with a Kp value of 0.120 at 25 deg C?
To determine the initial pressure of H2S gas in the flask, we need the total pressure and the partial pressure of another gas in equilibrium with H2S. Without the partial pressure of the other gas, we can't determine the initial pressure of H2S with just the Kp value and temperature provided.
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 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 state of OXYGEN at 25 degrees C?
Pure oxygen is a gas at 25 C, regardless of the pressure.
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 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 partial pressure of oxygen at boiling point of oxygen.?
um... the partial pressure at the boiling point always must be equal to the vapor pressure. This is true for all substances.Added:The partial pressure of a pure (100%) gaseous substance boiling from its pure liquid is 100% of total pressure, because its fully pure, so what else could be there.
What is the pKa of glucose?
12.28 at 25°C 12.28 at 25°C in water
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.
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.
