Find the mass of oxygen in a cylinder having a capacity of 100 liters at a temperature of 20 degree Celsius The pressure in the cylinder is maintained at 80 bar R equals 0.259859?
Let us do some conversions first, then use the ideal gas law. PV = nRT 1 Bar = 1.01325 atmospheres 80 Bar (1.01325 ATM/1 Bar) = 81.06 ATM 20 C = 293.15 K new R = 0.08206 L*ATM/mol*K (81.06 ATM)(100 L) = nI0.08206 L*ATM/mol*K)(293.15 K) moles O2 = 337 moles O2 * 32 grams = 10784 grams about 24 pounds of oxygen
How is desalination of water done?
Multi-stage flash distillationMulti-stage flash distillation (MSF) is a desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially regenerative heat exchangers. First, the seawater is heated in a container known as a brine heater. This is usually achieved by condensing steam on a bank of tubes carrying sea water through the brine heater. Heated water is passed to another container known as a "stage", where the surrounding pressure is lower than that in the brine heater. It is the sudden introduction of this water into a lower pressure "stage" that causes it to boil so rapidly as to flash into steam. As a rule, only a small percentage of this water is converted into steam. Consequently, it is normally the case that the remaining water will be sent through a series of additional stages, each possessing a lower ambient pressure than the previous "stage." As steam is generated, it is condensed on tubes of heat exchangers that run through each stage.Reverse osmosisReverse osmosis is a filtration process typically used for water. It works by using pressure to force a solution through a membrane, retaining the solute on one side and allowing the pure solvent to pass to the other side. This is the reverse of the normal osmosis process, which is the natural movement of solvent from an area of low solute concentration, through a membrane, to an area of high solute concentration when no external pressure is applied. The membranes used for reverse osmosis have a dense barrier layer in the polymer matrix where most separation occurs. In most cases the membrane is designed to allow only water to pass through this dense layer while preventing the passage of solutes (such as salt ions). This process requires that a high pressure be exerted on the high concentration side of the membrane, usually 2-17 bar (30-250 psi) for fresh and brackish water, and 40-70 bar (600-1000 psi) for seawater, which has around 24 bar (350 psi) natural osmotic pressure which must be overcome.Normally in osmosis when two solutions with different concentrations of a solute are mixed, the total amount of solutes in the two solutions will be equally distributed in the total amount of solvent from the two solutions. Instead of mixing the two solutions together, they can be put in two compartments where they are separated from each other by a semipermeable membrane. The semipermeable membrane does not allow the solutes to move from one compartment to the other, but allows the solvent to move. Since equilibrium cannot be achieved by the movement of solutes from the compartment with high solute concentration to the one with low solute concentration, it is instead achieved by the movement of the solvent from areas of low solute concentration to areas of high solute concentration. When the solvent moves away from low concentration areas, it causes these areas to become more concentrated. On the other side, when the solvent moves into areas of high concentration, solute concentration will decrease. This process is termed osmosis. The tendency for solvent to flow through the membrane can be expressed as "osmotic pressure", since it is analogous to flow caused by a pressure differential.In reverse osmosis, in a similar setup as that in osmosis, pressure is applied to the compartment with high concentration. In this case, there are two forces influencing the movement of water: the pressure caused by the difference in solute concentration between the two compartments (the osmotic pressure) and the externally applied pressure.Comparison between the twoThe more efficient method is multi-stage flash distillation and hence currently produces the world's largest quantity of desalinated water. However, MSF requires a large system and works mainly in industrial production, hence reverse osmosis is more appropriately used in homes as a smaller household system despite its lower efficiency, due to its far quieter operation and smaller mechanism.
What age did Fulton's ship boost America into?
Robert Fulton (November 14, 1765 â?? February 24, 1815) was an American engineer and inventor who is usually credited with developing the first commercially successful steamboat. With this, he ushered America into the Age of Steam.
How does temperature change E for steels?
Going cold, not very much - it may get a 2% higher at cryogenic temps. Going warn, it does decrease by up to 20% as you get to 1000 degrees F ( from 30 Msi to 24 Msi)
What is responding valuable?
Do you mean "responding variable"? In a scientific investigation, you try to change only one thing to see what happens. The thing you change is the manipulated variable (also called the independent variable). The result of this change is the responding variable (also called the dependent variable). For example, what if you measure the temperature of a beaker of water, then put it in the refrigerator for 24 hours, then measure again. The change in the temperature from the room to the fridge is the manipulated variable (you controlled it). Any change in the water temperature is the responding variable. It responded to the change you made.

How did the first steam boats work?
The first steam boat was made by Robert Fulton, it made its maiden voyage on August 17, 1807. Fulton's boat had a 24-horsepower Boulton and Watt engine that was controlled by the pressure of steam and a partial vacuum.
