what is a vapor lock?
413664
While you are traveling the high country this summer, and your car becomes weak, irritable, tired or just plan dead, it may be suffering from vapor lock.   \n\nVapor lock is the result of high altitude, high temperatures, or a combination on your car's engine. Vapor lock can occur at any altitude due to heat, but it is more common at higher altitudes, because gas at high altitudes vaporizes at a lower temperature. The resulting gas/air mixture can slow down or even stop the flow of gas to the engine, especially if your car is not designed for high altitude travel.   \n\nThe key symptoms that your car is suffering from vapor lock is a loss of engine power, a rough running engine, and/or a engine that will not start. To reduce the chance of vapor lock, avoid running the air conditioner, and at the first signs of power loss, shift your car into neutral and rev up the engine. Finally, be sure to shift to low gear when climbing.  \n\nIf your engine won't start due to vapor lock, here are a few good tips you may want to try to get it started:  \n  \n\nFirst, loosen the gas cap. Be sure to stand back when doing this because gas may spray out at you. \n\nSecond, remove the air cleaner cover and hold open the choke flutter valve in the carburetor with a object, like a screwdriver. Be careful - backfires can occur.   \n\nThird, start the engine, holding the gas pedal all the way to the floor - do not pump the gas.   \n\nFourth, wrap a wet cloth or cloth with snow around the metal fuel line near the carburetor (trace fuel line to make certain it goes to the carburetor).   \nFinally, let the motor cool at least 30 minutes before trying to start the car.

Relative humidity is a term used to describe the quantity of water vapor that exists in a gaseous mixture of air and water.\n\nDefinition\nRelative humidity is defined as the ratio of the partial pressure of water vapor in a gaseous mixture of air and water to the saturated vapor pressure of water at a given temperature. Relative humidity is expressed as a percentage and is calculated in the following manner:\n\nRH = {p_{(H_2O)} &#92;over p^*_{(H_2O)}} &#92;times 100%\n\nWhere symbols in the above equation have the following meaning:\n\n{p_{(H_2O)}} is the partial pressure of water vapor in the gas mixture;\n\n{p^*_{(H_2O)}} is the saturated vapor pressure of water at the temperature of the gas mixture; and\n\nRH_{&#92;,_&#92;,} is the relative humidity of the gas mixture being considered. \n\nYou could get more information from the link below...

Endothermic.   It takes (heat) energy to vaporize a liquid.\n\nThink of evaporation from the skin.  It feels colder when you're wet.   It takes heat energy away (endothermic) from your skin when the water evaporates.

A vat could also be called a tub: a large open vessel for holding or storing liquids. This one would be made out of glass. \n\nImagine a drinking glass that is shorter and bigger around than 'normal'

Its bound into a CloroFloroCarbons used in the "Freons"\n\nThe Freons are special molicules that are realitivly safe (Unless your an Ozone layer) and have BOILING points below the temprature you want to achieve.  Basicly There is a pump inside a air conditioner that compresses the gas until it becomes liquid where it gives off its heat *feel the back side of an air conditioner* then it goes through a tiny little tube and boils inside the tubes on the front side of the air conditioner *the one on the back is called a condenser, the one on the Front is called a evaporator based on if the freon is condensing or evaporating in it*

video the lockers.  (or spread a rumor that there is a security system)\nBuying stronger locks is a possibility, but a crow bar can handle most locks.

I would visit the site cited below.  The discussion includes:\n\n"Irving Langmuir developed a way to measure vapor pressure \nby measuring the evaporation rate, which we will now flip around backwards. His reasoning is that the rate at which molecues are lost due to evaporation to a gas with no partial pressure of the evaporating substance is the same as the rate at which molecules of the substance would hit the surface if it were in equilibrium with the vapor (because in equilibrium the evaporation rate and re-condensation rate cancel each other out). His expression is: \n\n(mass loss rate)/(unit area) = (vapor pressure - ambient partial pressure)*sqrt( (molecular weight)/(2*pi*R*T) ) "

It used to be used to stop the scrolling of a command line (hence the name). Most programs don't use it now.\n\nhttp://en.wikipedia.org/wiki/Scroll_lock has more information.

first vapour it all if there is no rubber monomer vaporize then try a distilation tower with hysys if u want i can simulate it for u?

the answer is pretty long!\n\nThe Scroll Lock key is a remnant from the original IBM PC keyboard. In the original design, Scroll Lock was intended to modify the behaviour of the arrow keys. When the scroll lock mode was on, the arrow keys would scroll the contents of a text window instead of moving the cursor as usual.Today, this particular use of Scroll Lock is rare. Only a few modern programs still honour this behaviour, such as Microsoft Excel (in the behaviour of arrows — when Scroll Lock is on, the selection does not move) and Lotus Notes. \n\nIn Linux command line sessions, the Scroll Lock key is used to pause screen output. This behaviour emulates the Hold Screen key or similar flow control mechanisms on computer terminals. Because of this emulation, the term scroll lock is sometimes used to generically refer to a screen pausing behaviour. This usage could potentially cause confusion since screen pausing behaviour is not intrinsically a part of the Scroll Lock key. In DOS, the Pause key pauses the screen output.

this has some lock diagrams. hope it helps

Raoult's Law describes a colligtive property.  It states that the more particles that are in solution, the lower the vapor pressure of the solution is.  For example, if I had a beaker of water out and I poured some salt in, the vapor pressure of the salt water would be lower than pure water's vapor pressure.  \n\nMathematically:\nVapor Pressure of the solution = (mole fraction of the solvent) * (Vapor pressure of the pure solvent)\n\nThe mole fraction of the solvent is found by dividing the number of moles of solvent by the total number of particles in solution.  \n\nRaoult's Law works because as more particles are added to the solvent, those particles that are being added block the vapor of the solvent from rising and escaping.  That means that the more particles added, the more vapor pressure blocking, and the lower the vapor pressure of solution.  \n\nRaoult's Law can also alternately apply to when two volatile substances (two liquids that evaporate readily) are mixed together. All you do to calculate total vapor pressure over the mixture is add the two vapor pressures together for the substances.

Cooling in the refrigerator. Drying clothes the vapor pressure changes exponentially. Populations and growth. (bugs, bacteria) Anything that grows in proportion to the amount.
