Well, now you know what it means . When you heat metal the energy from your heating device is transferred to the entropy of the metal you're heating . The metal gains mass and as a result of this expansion occurs , of course once you stop adding heat to the metal , the metal then contracts , the retained energy transferring to the environments entropy(s). The laws of thermodynamics , everything tries to retain an equilibrium , i.e room temperature .
And now you know how to spell "enthalpy" correctly. Entropy is another matter. Thanks for the attempted, basic education. The first week of welding school, covered it much better. Art thou a pseudo intellectual?
I am a fact intellectual and was trying to keep it basic , not knowing your ability , I am not sure you'd understand my interpretation and model of the Universe which is an advancement on Q.F.T . For that reason it seemed more appropriate to keep it simple and also my consideration was for other readers who may not be science minded . A simple thermodynamic map would be : A ⇨ B ⇨ C
Writing good English literature requires time , patience and concentration . Hastiness in writing will produce errors and misunderstanding of the content . A simple thermodynamic mapping would be : A ⇨ B ⇨ C I edited the previous post and added this simplistic mapping of the previously discussed entropy exchange .
It's not literature but basic English. If you are going to profess to lecture me on my field of expertise, you might learn basic English first. Until then, my opinion is set. Pseudo intellectual. Not the organ grinder. Good night...zzz
Heating metal adds mass to it? Wow! I'm going to grab a blowtorch and get rich off of my gold and silver!
Not totally... we all have seen and experienced it, heat does expand the mass, while cold contracts it. But that all things, like nature for instance, strive to maintain room temperature at all times is hard to see. It is pretty cold today where I live... the temperature is holding around the zero Celsius mark all day. The sun moves invisibly along its set path; the clouds don't care about letting the sun through... they just move along in an endless mass. Yes, the wind is maybe trying to work towards room temperature by not blowing at all. I know already from the past that winter is coming, that it will get colder still and windier... nothing will stop that process or slow it down. IF there was an effort somewhere to regain room temperature, I'm sure man would have discovered ways and means to help it along. O.k., now we are at Global Warming! Perhaps mankind did initiate that on purpose or it happened accidentally. Shouldn't we be elated to be able now to achieve room temperature across the globe? But no... we spend tons of money to slow it down, actually hoping to stop it altogether! Why? The gas and oil tycoons wouldn't make billions anymore! Oops, I forgot: Our bodies... yes, our bodies are trying hard to maintain a certain body temperature to sustain life. I'm so smart I amaze myself!
Wikipedia is a great starting point for research on topics one isn't familiar with. Much of it is true. But its prone to misconception and omission, and requires further research from other sources for more in depth understanding (as I would say of any source, really).
It is NOT academic standard and is at the whim of the editors but for simple clear explanations of basic facts it is one of the better resources on the net
So.......you do not believe in research or scientific methodology, will not accept inconvenient facts or anything that does not conform to your worldview??
I know! I'm just bsing, as there was nothing else to do. Now, don't take that as an admission... I'm still right!
