does milk count as water?

hydration is hydration. The many things that have water in them, including milk, tea, juice, coffee, even cola all counts towards hydration. Calories in them is another subject all together and some actually are better at hydrating than others. I have tried many times getting used to drinking water all day, but I just cannot do it. Since this is for life, I have changed to warm tea and drink a ton of it with a splash of milk. I am very hydrated. If your pee is a light yellow and not really dark then you are good as gold. We do get a lot of hydration from the foods we eat too. If you get thirsty that means your body is dehydrated, if you don't then you are most likely doing a good job.

*facepalm*

Water has one density, the density doesn't change dependent on state. The cup example is there are "less molecules" in the gas cup. If ther was the same molecules as the liquid cup then it would way the same. I think you're confused....

Quoted for the Lolz.

1 density?
My 10 years old knows better.

Here is the question. Why does ice float?

Because Water is what is known as H2O in a liquid state, Ice is known as H2O in a solid state. Water can't change state, H2O can.
The density of ice is 0.9167 g/cm³ at 0 °C, whereas water has a density of 0.9998 g/cm³ at the same temperature.

Notice the word "ice" and "water" so LOL

... And pressure.

You stated, "The density doesn't change dependent on state." You are now playing on semantics of water versus H2O. Nice try.
Your statement is wrong. Own it.

OK, my understanding is that we agree, but the initial comment was not well phrased and lead to all this discussion. Still, it's interesting and more fun than what I'm supposed to be working on right now

Just a couple more comments before I finally get back to work:

If you throw in environmental factors yes. For example what is pressure? It's a force, so yes it would cause an increase in weight.
Our environment is 1 atm as you know.

Ok, but I get the feeling from your response that you don't appreciate the importance of the "environmental factors". The density is NOT well defined unless the temperature and pressure are given or it's clarified that they are the same. This is especially true when you compare different phases (e.g. liquid/gas) of the same material.

((13.1326 mol.)( 0.08206 (L*atm)/(mol * K))(273.15k))/1 atm) = 292.12 liters or 1234.72cups.

in first glance the calculation is correct but you made a small mistake at the end: 1cup=1/4L not 4L! But we agree, you'd have ~300/4, about 75 cups of steam if 1 cup of water had evaporated and the T,P remained the same.

But Gases are just molecules that are excited, For example throw a can of soda in a fire what happens? The tempreture excites the molecules and causes them to move faster hitting the wall of the can faster with more speed, eventually it builds up enough speed to explode the can.

I won't elaborate but the statement in bold is also wrong Had I been grading I'd have taken some points off for that! What you mean is that molecules have higher kinetic energies, but they're not 'excited". That's something else

Just clarifying how gases work, now to the topic. I think we're misinterpreting each other, what I am saying... If you do consume 1 cup of H2O(g) you're consuming the same amount of molecules of H2O(l). Yes there is more Volume within a given container with a gas, but there is also a lot more space, the molecules are just moving faster within the container taking up more volume, the volume of water doesn't change. What changes is he space between the water.

Again, your phrasing is misleading. What you mean is If you do consume 1 cup of H2O that was liquid and then was all evaporated you're consuming the same amount of molecules of H2O(l)

With that I think we all agree. In other words, the same mass of water contains the same molecules independent of what its phase is. I think this is what you were trying to say but got mixed up with volumes etc

I saw the page what you posted, and yes that's not what I am talking about. In chemistry Dimensional analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique. The only danger is that you may end up thinking that chemistry is simply a math problem - which it definitely is not.

Interesting, I didn't know this had a name! Actually now that I think a bit more about it, it is in some way a very simple form of dimensional analysis and I suppose that's why it got this name. But it's still a misnomer. Out of curiosity and if you don't mind me asking, at which level is this taught (high school, college)? I'm not American but I'm somewhat familiar with the educational system over there.

Edit: I was going for a couple quick comments and close the issue, but ended up with a huge sentence by sentence reply. Sorry for that!

Milk is 85-90% water. http://wiki.answers.com/Q/What_percentage_of_milk_is_water

You can get "water" in many different ways.



Edit: The 8 glasses of water recommendation is an arbitrary number. It does not take into account water you get from food. The climate where you live. The energy that you expend daily. To much water can make your kidneys work harder than they need to. No one knows how much to much water is. Just like no one really knows how much water is required daily.

you're my hero.

You should not drink milk period, our bodies have not evolved yet for us to be used to this unnatural product. Also, if you are serious about working out, it increases the lactic acid build up in your muscles. Good luck.

WTF? Since when is milk an unnatural product? We didn't breed the cows to produce milk. They just do. As for that matter, is mothers milk an unnatural product?

Um, no. Tea and coffee are diuretics - they make you pee more water than you take in. They do not count.

Hi. Welcome to the thread. We disproved this a few pages ago. Perhaps you and the others would like to catch up?

if you are counting fluid intake.. yes you would. When in hospital and they are watching what fluids you take in, they count... water, milk, juice, pop, coffee, tea, soup, ice cream, apple sauce, jello, yogurt.

I think this has been commented to infinity, but I'm going to throw in my 2 cents anyway...

I don't count my skim milk intake towards my hydration intake (although I'm leaning towards the "do it" side of the argument). I don't count sodas, regular (caffeinated) tea, juices, green tea (again - caffeine), etc. However, I keep a jar of decaf artificially sweetened tea in my fridge and I DO count that and "crystal light"-type drink mixes, but only up to 4 glasses per day. I still try to make the majority of my liquids water.

Side note: I'm combining MFP with another plan that allows this type of hydration (up to 4 glasses of zero calorie, decaffeinated liquids).

And going back to the pee comparison: totally agree. If it's straw-colored or lighter, I know I'm good! (But I still don't drink it!!!)
