where does all the heat energy go?

Question

If all of universes energy is already here and we can only covert it from one form to another (example coal is converted into heat and that heat converted into electriity)

Well my guestion is where does all the heat energy go? when we convert fuel (gasoline) into conbustion energy in our cars a large amout of the energy is givin off as heat. that heat goes somewhere and with the millions of cars on the road that heat would have to accumilate somewhere.

The heat energy has to go somewhere or convert into another form. Where?????

Answer 1

Heat always goes to cool. And when it does, it itself is cooled down. Heat is when you excite molecules to a state of excitement which causes them to vibrate and release energy in the form of heat. Heat produced on earth goes up for two reasons. First the atmosphere pressure forces expanded air up like a heated balloon. Secondly heat travels to cooler places. Outer space is well below zero. In fact, if you were to travel far enough away from the sun, the temperature in space would be well below 400 degrees below zero Fahrenheit. 474 I believe, which is called absolute zero. All vibrating molecules which release energy in the form of heat, would slow down and simply stop movement. Outer space stops all energy and transforms it back to it's natural state. The reason for the green house issue today is carbon dioxide actually traps heat and won't let it escape into space and dissipate. It's like driving you're car down the road and you suddenly put it in neutral and slow down to a stop. You didn't change the car, Just the way of it's existence. Heat isn't transformed into another mater, it is simply transformed to another state of existence.

Answer 2

You are looking at it all the wrong way.

The energy in the universe is constant, meaning you cannot create or destroy it, you can only transfer it. So, in your car example, you transfer the potential energy that is stored in the fuel into kinetic energy of moving. During this process, the energy that is being used causes various parts of the car to heat up.

Now, just because we have no way to re-use this energy does not mean that it is destroyed. If we move away from the car example, and take a gas cooker, we have a way to re-use the energy given off as heat )by putting food on the cooker and using the energy to transform the food from a raw state to a cooked state.

Answer 3

well the heat is created by the movement of the small particles.
when the particles start moving
they start to collide with each other
when the collide
the heat is created

so when passing heat to one place to another
it passes through the particles

in simple theory
where energy cannot created or destroyed

the heat passes to the particles nearby
and the heated particles become cool

when this process happens
it goes for infinity and
ultimately the heat will be pass through out the whole universe

so the end it will go to the universe

the other question u asked about
whether it convert to another energy..............
it depends on the situation as u already know


take care

Answer 4

Don't forget that energy is also making your car move (kinetic energy) and your engine's probably loud - although muffled at the exhaust (given off as sound).

So it's not so much that there's a lot of heat accumulating everywhere, although that is the major problem. It's being converted into many different forms.

Answer 5

The heat energy produced by the combustion of cars is released into the atmosphere. This kind of energy contributes to global warming, along with greenhouse gases like carbon dioxide and sulfur dioxide.

Answer 6

the five heat transfer components balance out. mathematicall as follows
q1 = q2 + q3 + q4 + q5
q1 = heat generated
q2 = heat conduction
q3 = heat convection
q4 = heat radiation
q5 = heat storage

Answer 7

in the air, like leaving the door open trying to air condition the whole block.
it dissipates into the air,

Answer 8

Space the final Frontier' that's Where they say it goes,and yet Heat doesn't travel in a vacuum.

I'll be watching this, thanks for ????

Answer 9

Eventually it becomes what the astronomers call background radiation.

Answer 10

It's eventually radiated to space.
