I need to know .about where does energy(all forms) lost(dissipated)go.....?

Question

People say that ......when friction is undergone.....somewhat is used as Mechanical Energy,,,,,other decipated as "Joules Heat"....thats totally fine BUT WHERE DOES THE HEAT DISSIPATED GO???????...well...we can say it goes into the atmosphere..but WHERE into the atmosphere......some perculation point??....some point where this energy gets used up in some form of evaporation of water.....or even Fission??? ..plz si need help

Answer 1

When heat is released due to friction, the heat or lost energy is dissipated to the surrounding enviroment, which is most likely the air in the atmosphere. This lost energy in the form of heat basically causes kinetic motion in the air molecules, some of which will be water molecules (this would correspond to evaporation of water). This means that the air molecules moves around very fast when it is heated, and heated air rises up, thus creating air currents. Eventually, the energy in this atmospheric molecular movements is released into space as photons in the infrared frequency range.

PS - I don't believe fission actually happens this way since heat or infrared photons are not energetic enough to cause fission reactions.

Answer 2

Imagine a balloon which is burst. Where does the air inside it go? It is spread out into the space around the balloon.
When energy is transferred from one type to another there is never 100% transference, some energy is lost in the form of heat. This heat is transferred into increased kinetic energy of the surrounding molecules and so becomes spread-out and unrecoverable (increased entropy). But this can only happen if there is more energy in one place than another (an energy gradient); energy will move from a region of higher energy to one which is lower (a bit like a ball rolling down a hill).
A suggestion for the end of the universe is that all energy will become evenly spread out. This will mean no gradients and so no action/effect/movement. This is called 'the heat-death of the universe.'

Answer 3

The atmosphere is made of gasses, Nitrogen, Oxygen, Carbon Dioxide and others, so your dissipated heat energy is absorbed by these gasses on an atomic & molecular level. But, the capacity for the gas surrounding us to to absorb this heat is usually much greater than the amount of energy given off by most processes. The amount of energy required to change the temperature of a gas by a certain amount is called the gas' heat capacity.

Some heat energy is ultimately radiated back to space. Some will stay within the atmosphere and (like you mentioned) be transferred to water causing it to change phase from liquid to solid (evaporate). There is a good discussion of heat on this Wikipedia page:

Answer 4

It just ... dissipates. It spreads out through the environment. So as your brakes cool off, the atmosphere is heated by some infinitesimal fraction of a degree, as a little bit of heat is absorbed by a lot of air. This dissipated energy doesn't build up over time because our planet is in thermal equilibrium - excess heat is eventually radiated into space.

Answer 5

heat energy makes moluecules "energetic" So those molecules move faster. That energy is then transfered to the next molecule and so on. This energy is then transferred until it is absorbed by something else, like a windmill. btw, heat also creates differences in pressures which also leads to wind/water movement and many other things.

Answer 6

Hypothetically the energy will eventually leave the atmosphere and travel through space, from there it will flow toward a black hole/s after which it may compress and transform to bottled energy or mass as we commonly know it.

Answer 7

Dissipated heat doesn't -go- anywhere. It's just that the heat energy is distributed throughout the atmosphere.

Answer 8

Heat moves from a source to a sink. The greatest sink we know is water and it is in the oceans which act as a thermal balance for mother earth.

Answer 9

Back into its universal source, the Supreme (what ever name u like to call it )!
