This Has Me Stumped (Math Problem)

[DanG]

Ambient temp,90°F.  Sitting in shade with a fan blowing on me from the right rear quarter.  8 steps to the rental cooler, 14 to the return tree.  Unlimited supply, come on down.

I'll be right there. But I am kind of slow so it might take a while. That 90 degrees F sounds good to me right now. I think it was only in the low 50's this morning.   

[Jeff]

I'll take the low 50's

[DanG]

Yeah, I was gonna suggest that he bring some of that with him.  I recall having longed for warmth just a few months ago, but I could use a dose of cool right about now.

Phase change is a big thing in globle waming, with polar ice caps. But think the oceans in FL. is ging up from DanG. We will have to get busy up north, so we can keep the water even.

SO

heat is the total amunt of energy of all of the particles in a sample

and temperature is the average amount of enegy of a single particle





the consumed beverage will rapidly warm to the average kinetic energy of the particles it is now stored close to, the passage rate of five minutes seems to be a bit high and would depend on much more than height and weight, more like age and rate of consumption.  too bad there isn't a national call for recycled beverage consumption.

this concept was very hard to teach to high school students

my favorite demonstration was boiling water in a paper dixie cup using a bunsen burner.  the water could extract the heat so fast that the cup did not burn.  I still run into ex students(some 40 years old now) who turn to their wives or husbands and say....thats Mr Mills the teacher who boiled water in a paper cup
[/quote]  ill be jump in a creek. never heard of that before. learn something new every day!!!!!!!!!

my favorite demonstration was boiling water in a paper dixie cup using a bunsen burner.

I once did it using a paper bag over a campfire. Did it to win a bet .

I like to throw old christmas trees, one at a time, over the top of a raging bonfire.  They kinda levitate a fot or so over the wood and burn like mad

Here is a trick I learned at the adventurers club on pleasure island at disney

take one empty liquor bottle 86 proof or better
warm the bottle with hot water, but don't get water in the bottle
take a plastic coctail straw and put a tooth pick through it a little above the center
put the straw in the mouth of the bottle resting on the tooth pick
drop a match into the bottle and watch the straw take off like a rocket.

woodmills1, that was a great explanation on the energies involved with state changes.  You should write up your thoughts on those observations when considering entropy. 

DanG...  the truth is, you've been working even harder than you thought.  See, you aren't just heating said beverage up to 98 degrees before expelling it.  You are also changing part of it into a gaseous form (hence the fan blowing on you from the right rear quarter to dispense the poisonous gas before innocents are harmed).
