What is the difference between dehydration and drying?

Drying means to get rid of the free water in a given compound. For example: you would be drying your clothes. But dehydration means to get rid of ALL the water in a given compound. In example: You have a fresh lettuce leaf... You wash it and then you dry it... You'll have a lettuce leaf as it is. Then, you cook it (because you're nutz and like cooked lettuce for dinner), and have some black things like ashes. THAT is dehydration =)

you can take some rice, boil it, and just before the water gets absorbed by the rice put it in a cup and drink it.  also bananas and toast will help dry you up. go cautiously because the rice water will realy plug you up then you will have the opposite problem--can't go.

H2SO4 will dehydrate and remove water.\n\n\n(CH3)2 CH - CH2-CH=CH-(CH3)2

The minerals and salts in the water dehydrates the body the more water you drink.

Wet is good, wetter is better, dripping wet is great.\n\nDry is the problem, not wet.\n\nNo, it doesn't slip out because of being too wet. It slips out because of movement. We enjoy getting it lined up and putting it back in anyway.

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.

It keeps your body hydrated.  When you're ill you tend to have a fever and lose a lot of moisture.  Staying hydrated keeps the body's systems running as smoothly as possible, allowing the illness to progress without complications that can come from being dehydrated.

water water water.  dry lips are one of the first signs of dehydration.

Oddly enough, by drinking a lot of water. Your body retains water when you dont drink enough, or when you eat enough salt to cause it to become dehydrated. It holds onto whatever fluids it has...\nTry drinking a LOT of water...60 oz per day....

Hot air *can* contain more moisture than cold air, but it depends on how much moisture is available for it to contain.

the apple would dessicate, or dry out, as the water converted to vapor.  This conversion would be hastened by the low pressure, since the energy of vaporization is proportional to pressure.  So you would get a dried out apple relatively quickly.  But it would not rot because bacteria and fungi cannot survive in a true vacuum.

Paper contains acid that was used in making it. Water is a solvent, that when it comes in contact with the paper immediately begins to break down the fibers. Oil, on the other hand is inert, and does not break the fibers down. Just as a sidenote though, ever notice how cotton clothes are harder to rip when they are wet?

A dry cell only has one comparment which uses a one solution where a voltaic cell has two seperate compartments for two different half reactions. They both have a catode and anode to conduct the electricty, but half cells are more expensive. The two have the same purpose though and that is to conduct electricty and also to produce a small current.

The actual reason that alcohol evaporates quicker than water has to do with vapor pressure.\n\nAll liquids have a certain amount of vapor at the surface of the liquid.  Since the intermolecular forces are weaker within a smaple of alcohol than within a smaple of water, there is more vapor present above the surface of alcohol than above the surface of water. The more vapor above the surface, the higher the vapor pressure.  The higher the vapor pressure, the faster the rate of evaporation. \n\nSince there is more vapor present above the surface of the alcohol, more molecules will randomly leave the surface and go into the air surrounding the container.  This is the process of evaporation, which is different than boiling.  The two are related, but not the same.\n\nThis difference in rates of evaporation has nothing to do with the heat capacities of water and alcohol.

Silica gel is used to absorb water from a gaseous environment the water absorbing capacity is usually around 25% by weight, \n\nso it absorbs the water in human body causes dehydration

Oil would evaporate slower.  The reason is not what it has in it to make it evaporate but rather the temperature at which a substance evaporates, and how much energy is needed to maintain that temperature while it evaporates.  Vinegar is much less dense than oil and evaporates at a lower temperature and therefore requires less energy to fully evaporate than the same volume of oil.

the tearing of the paper when dry allows you to hear (literally) the pulling apart of the molecules of the paper...after all, it is a solid, and you are disrupting its structure.  \n\nThis is also true when the paper is wet.  The difference is that the water "dampens" (no pun intended) the sound waves.  The moisture of the water also weakens the molecular bonds within the paper and allows a quieter seperation.
