A beaker contains 0.4% sucrose solution. A 0.1% sucrose solution is in a dialysis bag. What is the potential pressure of the system if the beaker is open to the atmosphere?
Wow. You are quite not-so-intelligent. You continue your question in the spot that's for the answer. Well then how do you expect someone to answer this question? I myself am looking for the answer, and by doing this, I am furthering the inability for someone to answer this question. Well I hope you continue to be in your ignorant bliss and I hope you found out the answer to this question. If you did, why don't you drop by and tell me the answer? Jeez.
The shaft seal in the open drive type compressor is particularly susceptible to leaks in low-pressure refrigeration systems. This seal is exposed to the atmosphere and can deteriorate over time, leading to refrigerant leaks. Regular maintenance and monitoring of the seal can help prevent leaks in the system.
Chiller tubes
Basically, because the atmosphere has weight. There would be no weight without gravity. Earth's gravity is pulling the atmosphere down toward earth's surface. We live on the surface, so the atmosphere pushes on us.
The decomposition of calcium carbonate in an open container is irreversible, because one of the decomposition products, carbon dioxide, is a gas, and since the container is open, this gas will mix with the natural atmosphere and never develop sufficient local partial pressure to reverse the reaction.
the Nernst potential of Sodium is +60mV. most action potentials do not reach +60mV at peak depoloarization. http://openwetware.org/images/thumb/a/a6/Action-potential.jpg/300px-Action-potential.jpg.png
The pressure potential of the system in an open beaker is equal to atmospheric pressure, typically around 101.3 kPa.
a common manometer is a u-tube with a liquid filled about half way in each leg, one end is open to the atmosphere and the other connected to the thing that your measuring the pressure of, as the pressure increases, the liquid in the leg attached to your pressure of interest is forced down, and the pressure in the other leg is pushed up, because you are comparing it to the atmosphere it is a gauge pressure in comparison to the atmosphere =] hope this helps.
"Never heat a capped vessel." In both these steps a container is being heated and if not open to the atmosphere, pressure could build up inside and make the vessel explode.
The Liquid will turn into gas. The boiling point corresponds to the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. If the liquid is open to the atmosphere (that is, not in a sealed vessel), it is not possible to sustain a pressure greater than the atmospheric pressure, because the vapor will simply expand until its pressure equals that of the atmosphere.
One of ends of the tube is used for pressure measurements, the other can be left open to the atmosphere to measure static pressure, or can be attached to the low end of a pressure system to measure differential pressure.
A sol'n under HIGH pressure has more gas in it. The high pressure is working against the much smaller vapor pressure of the liquid. If they equal then the liquid is at it's boiling point. Additionally applying pressure to a solution keeps dissolved gasses inside the solution such as Oxygen or Carbon Dioxide (Think of a Cola can. It is stored under pressure and the fizz stays in the liquid. Then you open the can and release the high pressure and the carbon dioxide starts to bubble out of the solution. It was not doing this before you opened the can and lowered the overall pressure)
A pressure switch failing open can lead to increased energy consumption, equipment damage, and potential safety hazards, resulting in higher maintenance and repair costs, as well as potential downtime and loss of productivity. This can ultimately increase the total cost of ownership for the system.
Pure Water has potential of 0.If more solute is added to it water potential falls-it becomes more negative
I guess it depends on whether it's sealed or not. If it's open to the atmosphere how can it be under pressure ? If it's sealed it could be put under (positive or negative) pressure so would be, by definition, a pressure vessel IMHO.
It is a type of manometer, an object used to measure the pressure of different things, and the open armed manometer allows for the atmospheric pressure in the tube of the manometer. So the sample gas pressure pushes on the mercury that is already being pushed on by the atmospheric pressure. Then you add the atmospheric pressure to the change in the mercury (in mm) and that gives you your pressure. It's like a tire gauge.
It is a device that measures the differential pressure between two inputs. Example: You have a pressure container where you connect the H-side (high) of the DP-cell. The L-side (low) you leave in the atmosphere (open air). The DP-cell will tell you the pressure in the pressure container relative to atmosphere pressure. Depending on what class the DP-cell is, it will give you feedback with a current signal. Normal in Europe is 4-20 mA, where 4 is lowest and 20 is highest.
The open circuit (oc) potential is the potential of the working electrode relative to the reference electrode when no potential or current is being applied to the cell.
