why must you keep the cap on the bottle? (in relation to condensation)?

If you don't, some of the water will evaporate into the air, so it will seem like you "lost" some water.

Like everyone else said, it makes the drink cooler. However, this is because heat is transferred in an attempt to achieve equilibrium. In this case, the equilibrium would be between the temperature of the ice and that of the drink. Because the average temperature of the drink is higher than that of the ice, heat flows out of the drink and into the ice, slowly levelling the temperature.

It works by removing the water vapour (like steam) from the air. Water vapour condenses back to a solid for when it meets a cold surface. The water then appears as if from knowhere (as in condensation on a glass or can containing a cold drink) This action takes place when the dew point of the vapourised liquid is reached

I think condensation.

Hi. Usually to minimize pressure variations in a home's water system. Fire extinguishers, aerosol cans, Coleman stoves, etc. all use them to store potential energy.

Several theories are available on this problem, depending on the specific situation: \n\na)  In structured, porous solids, "ink-bottle" pores can traps adsorbates.\n\nb)  Irreversible changes may occur in the pore structure on adsorption, so that the desorption situation is different from the adsorption process.\n\nc)  Contact angle hysterisis due to impurities.\n\nd)  Formation of multi-layers of adsorbate, so that the curvature of the surface changes.\n\ne)  capillary condensation phenomena

Condense?\n\nSounds like you have to read the rest of the question. :)

Glue doesn't stick to the inside because in order to dry, glue must lose its moisture, and it cannot while still inside of the bottle.  Leave the top off and the whole thing will dry out and get stuck\n\nFlies get inside of the lights because they aren't sealed air tight

When you freeze water it expands, which increases it's volume. With a closed bottle, the pressure gives the expanding water no where to go, therefore the bottle must expand with the water, making it explode.

You store things in it. And sometimes you put a plug in it, so it can't leak out.

It is now clear who is asking for the limit of 3 degrees. Is it the turbine manufacturer, surface condenser manufacturer, or someone else?\n\nI assume the condensate is being pumped. Is it the condensate manufacturer that is asking for the limit?\n\nI would think from a heat conservation standpoint, you would want to keep it as close to the condensing temperature as possible and still be able to pump the condensate.

Best when the cup can surround the can including from the bottom. Also, keep in mind your hand transfers heat into the can so if you plan on holding the can have the cup underneath.\n\nBesides, if the cup were on the top, each time yon wanted a sip you would have to remove the cup with your other hand, which is very inefficient of your time and energy.\n\nYou need to look at the entire problem not just from the perspective of the can sitting there.

You might work up some Q&A while showing this old demo of the effect of atm pressure...thereby adding some visual interest to the subject.\n\nAdd a few oz of water to a square-sided, metal, one-gallon can having a tightly fitted cap...bring to a vigorous boil (cap now off, please :-))..) and continue boiling until all air is expelled...screw cap in place and allow to cool...they will see the can collapse.\n\nWork up questions about the vacuum thus created (by the condensation of the water vapor) allowing atm pressure to exert its force.

Remember:\n\nH2CO3 <----> H20 + CO2 is an equilibrium\n\nThe bottle is pressurized with carbon dioxide, so the equilibrium is shifted towards the formation of carbonic acid. When the bottle is opened, the pressure of CO2 drops and the CO2 equilibrates with the atmosphere. That shifts the equilibrium to the right, and the drink slowly loses its carbonation. When you close the top, enough CO2 is created to recreate the setting of the equilibrium and most of the H2CO3 remains.\n\nThe biting taste is from the carbonic acid.

Same reason a water bottle will crack(water expands when frozen), the only difference is the carbonated drinks aren't completely frozen so it leaks everywhere.

both will have a miniscus and this is due to the adhesive property of water. the cohesive property keeps the water molecules togherter but the adhesive props allow for movement as in a cappilary tube. the gLass is clearer than the plastic so im thinking glass

"Take an appropriate container to the reagent shelf where the liquid is kept. Make the actual transfer at a nearby sink to avoid spills on the laboratory bench, shelf, or floor. \nIf the general supply bottle is equipped with a dropper, use the dropper, but be sure that it never touches the container or its contents, as shown in Figure 3.\nIf the general supply bottle is equipped with a stopper, the stopper should either be held during the transfer or placed on its flat top. Do not lay the stopper on its side on the laboratory bench or shelf. The proper technique is shown in Figure 4. \nDo not put your dropper or capillary pipette into the general supply bottle. Pour chemicals from the general supply bottle into a labeled container for personal use. \nBe sure the appropriate stopper is returned to the supply bottle. \nUse a clean dropper to dispense liquids from your labeled container."\n\nSee more information and diagrams at the site below.
