The total pressure in a flask is the sum of the partial pressures of all the gases present in the flask. It can be calculated using the ideal gas law equation, PV = nRT, where P is the total pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.

When the water level is higher inside than outside the flask is the gas pressure in the flask higher than lower than or the same as the atmospheric pressure?
When the water level is higher inside than outside the flask, the gas pressure in the flask is lower than the atmospheric pressure. This is because the weight of the column of water inside the flask creates an additional pressure on the gas inside, reducing its pressure relative to the atmospheric pressure outside.
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.
Assume you seal 1.0 g of diethyl ether in an evacuated 100 mL flask If the flask is held at 30 degrees Celsius what is the approx gas pressure in the flask?
At 30 degrees C, the vapor pressure of ethe is about 590 mm Hg. (The pressure requires 0.23 g of ether in the vapor phase at the fiven conditions, so there is sufficient ether in the flask.) At 0 degrees C, the vapo pressure is about 160 mm Hg, so some ether condenses when the tempeature declines.
What becomes when 300ml in a container 'n' 1000ml in a flask?
The total volume in the container and the flask is 1300 ml.
What happens to air pressure inside the flask if water levels are not equal?
If the water levels are not equal, the air pressure inside the flask will be higher on the side with the higher water level. This is because the weight of the water creates a greater force on the air below it, increasing the pressure.
Why did the water rush into the erlenmeyer flask when it was submerged in the cold water?
1. When the flask was placed into the cold water, the colder air molecules in the flask move slower, putting out less pressure. With the decrease in air pressure inside the flask, the now greater pressure outside pushes water into the flask until the pressure inside equals the pressure outside.
When the water level is higher inside than outside the flask is the gas pressure in the flask higher or lower or the same as the atmospheric pressure?
When the water level is higher inside the flask than outside, the gas pressure in the flask would be lower than the atmospheric pressure. This is because the water exerts a partial vacuum on the gas in the flask, reducing its pressure compared to the external atmospheric pressure.

When all the liquid has evaporated the vapor totally fills the florence flask and exerts a pressure equal to the atmospheric pressure why?
I'm guessing you are analyzing an experiment where you are determining the molecular mass of an organic liquid. You heated the flask and the liquid evaporated filling the flask, but escaping through a small hole in the covering. 1. Gases always fill the container. So, if the liquid evaporated and formed a gas (vapor), it filled the flask, 2. The pressure on the outside the flask is air pressure. since the vapor isn't pushing off the cover, the pressure is not higher than the air pressure. But since the extra escaped, it cannot be less than the air pressure. Therefore, it is the same.
Why is the student unable to blow up a balloon in the flask?
The student is unable to blow up a balloon in the flask because there is already air present in the flask, creating a high pressure environment. When the student tries to blow air into the flask, the pressure inside the flask increases, making it difficult for air to enter and inflate the balloon.
If you cool a flask to -200degrise what would happen to the air?
I the flask was sealed, the air inside of the flask would take up less space and as a result, cause a drop in pressure inside the flask.
A sample of nitrogen gas is stored in a 500.0ml flask at 108kpa and 10.0c the gas is transferred to a 750.0ml flask at 21.0c what is the pressure of nitrogen in the second flask?
To find the pressure of the nitrogen gas in the second flask, you can use the combined gas law equation: P1V1/T1 = P2V2/T2, where P1, V1, and T1 are the initial pressure, volume, and temperature, and P2, V2, and T2 are the final pressure, volume, and temperature. Plug in the given values to find the final pressure of nitrogen in the second flask.

Sam filled a 500ml conical flask with 200ml of water Then he attached a 100ml syringe full of air to the conical flask and pushed the plunger inwards What was the volume of air in the flask?
The total volume in the flask is 500ml of water + 100ml of air from the syringe, which equals 600ml. Since the 200ml of water takes up space in the conical flask, the remaining volume for air is 400ml.
