Mayoflyfarmer, that is a good explanation now I need to think a bit. I understand the cold thing I think.
 I am slow going on the Joules, was that some kind of a unit of measure, I don't recall exactly.I remember something but not enough to get me by on that one. Too long ago , Please enlighten me!

 Neil you are too funny, you need to be careful what you are rubbing up against out there in the cold, It might bite! Not to mention it might have rabbies! You might find your coffee a bit too coarsely ground sir!

..thing is...will it work with my ribbed Black & Red Luminous condoms ?

That is quite a conundrum -- moan ..... Not that way, you nit!

yes karen, joules (as well as calories) are a unit of measure that we use to measure energy in.  just like we use meters or inches to measure distance, and seconds to measure time, and pounds and grams to measure mass/weight.  

just like all of the above stated units claories and joules are an aritrary amount of energy. but they serve as standardized units so that you can describe an amount of energy and someone will know whow much you mean.

Thanks, I could not remember that far back into my schooling. Dang! there must me a brain in here after all these years! I thought I lost track of it about 25 years ago. Nice to know I can remember something, and even nicer to know you guys are there to help pull up these things and help me when I fail! I took a physical science class in high school, which was fun until they began disecting frogs and other more disagreeable items. So this forum is great!

[moonfire]

I am just amazed at the different things used as a lens...but this is the first time I have heard of a condom for such..Robert, I must say, I am amazed at your intelligence and the massive knowledge you have!

I do like Mayofarmers analogy though...thanks so much!

Hi Loretta, Glad to see you back! How was the trip, Did you find any Tame polar bears out there for Neil?

[moonfire]

Hey Karen!  Trip was fine once I left Vegas and went to the desert to explore and ran across a little Tortoise....they can withstand heat up to 140 degrees...amazing!  I guess I could've covered him with some white fur and put a black nose on him and handed him over to Neil..hehe

Those tortoise can give you a nasty nip !! []  OUCH !!!

They sure can, we would have had to put a muzzle on it for you!

But you should be careful when using calories, since what nutritionists refer to as calories are really kilocalories.

What is the difference between calories and Kilocalories?
  No worries, Personally I don't count calories, if I like it I have a bit. I used to have a lot, but these days I am doing some serious portion control instead of counting calories. I hate math.

A factor of 1000 (kilo being the SI prefix for 1000, although it may be argued that calories are CGS units rather than SI units).

If you don't have a condom handy then you can start a fire with a can of coke and a chocolate bar:-

thanks for the clrification someone

just to elaborate.  the reason the word calories is used in the contex of heat and nutrition is because they are reffering to the same thing.... ENERGY (hence the term burn the calories off)  when you eat food the number of calories equals the amount of energy taht your body gets to generate heat (among other things such as metabolic processes, growth etc.)  This is why on the back of a Gatorade botle if you look at the nutritional information, next to the word "calories" they have in parentahses "energy", because people are used to calories being a bad thing, but when you're trying to refuel your body, its exactly what you wnat.
In theory if you were to take a slice of bread that (nutrtionally speaking) had 100 calories, and burn it instead of eat it, you would get generate 100 calories of heat.  Granted, you would actually get 100,000 calories of heat because as Another Someone pointed out, that what nutritioists call a calorie is actually a kilocalorie in sentific terms (ie 1 calroie in a can of diet coke actually equals 1000 calories)  

i just had a thought.  wouldn't it be funny if all of a sudden food packaging started displaying actual calories instead of calling Kilocalories calories.  You'd have a lot of calorie-counting dieters going crazy!!!  I personally never saw the point of counting calories myself.  The COMPOSITION of what you eat (ie what proportion of the calories come from fat/protein/carbs) and limiting harmful molecules such as cholesterols, saturated fats, and dyes and perservatives is so much more important than teh amount you eat.

Actually, I think you would get far more that 100 kilocalories if you burn it.

The silly thing is that the calculation of calorific values of food makes lots of assumptions about the human metabolism (which is ofcourse different for each individual).  A nutritionist would assume a lump of aluminium has no calorific value, but clearly it can be burnt in air, but unable to be digested by the human body.  A field of grass may have a significant calorific value for most cows, but not much for the average human digestive system.

Technically heat is the MOVEMENT or transfer of energy, to precieve that something is warm, you have to feel the heat coming off of it which means that it is moving.  For instance if you wrap your hands around a warm coffee mug and it feels warm.  This is because the mug the molecules in the mug are at a higher energy state than the molecules in your hand.  as things tend twoards equilibrium the energy from the mug will leave the mug and enter your hand.  (you sense this energy coming into your hand as heat).  The mug will feel warm until it had equilibrated with your hand, inwhich case the energy levels are aqll the same, so there is no more net flow of energy.

So, we can transfer the heat in our mug to our hand. Say, if I want to warm down a hot beverage, can I stick a ribbon to the cup so that the heat gets transferred to the ribbon?

A strange burst of interest in this thread after 13 years !. cold is the natural state of things heat is something you can add of course if you want to get out a useful amount of energy from a source that may well be free such as the 30°sea water at the tropics or the exhausts of your Diesel engine you need to spend money to pump up cold water from the deep ocean or build cooling towers next to your power plant.
