"In fact physical, chemical, and electrical energy can be completely changed into heat. But the reverse (heat into physical energy, for example) cannot be fully accomplished without outside help or without an inevitable loss of energy in the form of irretrievable heat. This does not mean that the energy is destroyed; it means that it becomes unavailable for producing work. The irreversible increase of this nondisposable energy in the universe is measured by the abstract dimension that Clausius in 1865 called entropy (from the Greek entrope, change).
There seems to be a contradiction between the first and second principles. One says that heat and energy are two dimensions of the same nature; the other says they are not, since potential energy is degraded irreversibly to an inferior, less noble, lower-quality form--heat. Statistical theory provides the answer. Heat is energy; it is kinetic energy that results from the movement of molecules in a gas or the vibration of atoms in a solid. In the form of heat this energy is reduced to a state of maximum disorder in which each individual movement is neutralized by statistical laws. "
Have fun.

you make me miss mechanics and thermodynamics. Or not... :P

As i said to you when you were online, EVER HEARD OF HEAT WAVES?!?!?!?!?!?!?!?!!?QUESTIONMARKONEELEVEN
-
how does that statement change what fatalbone said sintrael?
what we call a heatwave is a range of days with very warm weather :)

Goza bored @ work yet again!
-
thats the problem with working in IT. Its good money its easy. but it gets BOOOOORING.
-
And that's why we have IRC, forums etc.
-
Yea I remember that. what about them sint ? afaik that means very hot weather days l grax said. Could find anything in wikipedia too. If it is sarcasm, its rather vague.
-
i remember when i did physics my teacher blabbing on about how heat can travel in waves, like radiation can make things hot. honestly i cant remember wtf they are but that they exist. Pretty sure that the heat we feel from the sun isnt hot atoms flying all the way thru space and hitting us
-
idd they are not. but light that hits atoms get either absorbed or reflected.
absorbed light produces heat. like when something black lying in the sun becomes hot. when the material gets hot it is actually its atoms beginning to move.
What you remember from school physics is light not heat.
there is a particle and a wave theory for how it moves.

omg n3rd5!

This qualifies as the most boring thread I have ever read on any forum anywhere.
Congratulations.

Casuals learn to study science!
Science brought us such stuff as atom bombs, microwave ovens and world of warcraft!

All immensely cool, and cooking has never been easier! :D
