Heat can usually be considered as the energy of motion of atoms and molecules.
Heat can flow spontaneously only from warm to cold.
Heat can be made to go in the other direction, but only by doing work.
So, the simple answer is: from warm to cold.

∙ 12y agoA fundamental concept of thermodynamics is that heat will flow from where it is hot to where it is cool. Another way to say this is that heat moves from where it's hot to where it's not. This is always the case, and is the driving force behind the flow or movement of thermal energy.
Something that needs to be understood is that from a thermodynamic perspective, heat is only heat when the energy is in transit. By analogy, rain is only rain when it is falling. Before it falls, it is a cloud, after it lands, it is a puddle or a river or a lake etc. A hot object does not have "a lot of heat" nor is it correct to say that it is "high heat" - it has a lot of internal energy. Changes in the internal energy of an object are manifest as changes in temperature. Heat will flow between a high temperature and a low temperature so it could be said (informally - and incorrectly) that heat flows from "high heat' to "low heat" if you define high heat as high temperature and low heat as low temperature.

do you set it on a fire, or on a pile of ice cubes ?
Heat always flows from a higher temperature to a lower temperature, hot to cold.
Look at it this way, when it's cold and snowy outside and your kid leaves a window open they are letting the heat escape. Your warm and toasty heat coming from the furnace is going right out the window, along with the money in your wallet because now the heating bill went up.

∙ 11y agoNO . IT CAN ALSO FLOW FROM COLD. EX -AC it takes hot air from outside pushes
the air inside the room . the air is converted from hot to cold.

Sorry Hari. There are several different processes going on inside the air conditioner,
heat pump, furnace, or refrigerator, and at each and every step along the way, the heat
always flows from hot to cold.
When you get right down to the laws of nature that control the flow of heat,
it turns out that there's no firm law that says it must flow from hot to cold, only
a probability. But the chances of heat flowing in the other direction are so small
that hot ---> cold is handled as if it's a law of nature.

What happens to hot and cold objects when they brought together?
If heat can flow between them, then heat flows from the hot one to the cold one. The temperature of the hot object falls, and the temperature of the cold object rises. What drives the transfer of heat is the difference in temperature, so as soon as both objects are at the same temperature, the process stops, and no more heat is transferred.
If two systems at different temperatures have contact with each other heat will flow from the system at?
40 C to 293 K Heat always flows from hot to cold.
What is cold heat?
Hot and cold are used as comparatives. Almost anything can be hot or cold depending on what you compare it to.
In which direction does heat transfer?
The direction that heat flows in is From a warmer object to a cooler object.
What way can heat never flow?
From cold to hot.
What way can heat flows?
From cold to hot.
Does heat energy flows from colder to hotter?
No heat does not flow from colder to hotter. It flows from hot to cold.
Heat never of itself flows from a cold to a hot substance?
Heat can flow from cold to hot substances. It's flow depends on the total amount of heat of the substance not on the temperature. It flows from the substance which has more heat to the substance which has less heat stored in it.
when a cold object is touched state whether the heat energy flows from the person's hand to the object or the object to the person's hand and why is it so?
Heat always flows from hot to cold. Cold is the absence of heat.
When heat flows from a hot area to a cold area it is called?
It\'s still called heat.
Which way does heat flow?
Heat flows from hot to cold. This is because molecules spread around and it goes from hot to cold until thermal equilibrium is reached.
What law of thermodynamics state the fact that heat flows from hot to cold?
geometric shape
How does always flow?
heat always flows from hot to cold. ps, are you in mrs. ritters class???
How does energy flow in relation to hot or cooler bodies?
Heat energy flows form hot to cold body naturally.
If you left something cold on the counter how does heat flow between the cold item and the counter?
Heat always, and only, flows from a hot item to a cooler one.
Which way does heat transfer?
Heat always flows from a hotter object to a colder one. So: Heat 'transfers' from 'hot' to 'cold' (cold being a relative term and considered an absence of heat).
Why heat flows from hot body to cold body?
Heat flows from hot to cold because when hot and cold bodies contact with each other (thermal contact), the fast moving molecules of the hot body collide with slow moving molecules of the cold body; therefore the molecules of hot body become slower and body becomes cool, and the molecules of other body (cold) becomes faster and the cold body becomes hot. Notice: when molecules of a body moves faster it's kinetic energy increase therefore temperature increases and it becomes hot.
