A 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.

Well, let's see ... if you need to boil a pot of water,
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.
NO . 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.
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.
When heat flows from a hot area to a cold area it is called?
It\'s still called heat.
What type of heat transfer occurs when hot water flows through cold water?
Convection is the type of heat transfer that occurs when hot water flows through cold water. As the hot water moves through the cold water, it transfers heat energy to the surrounding cold water, causing it to warm up. This results in a transfer of heat through the movement of the fluids.
Does heat energy flow cold to hot?
No, heat energy flows from hot to cold in order to reach thermal equilibrium. Heat transfer occurs until the temperatures of the two objects are equal.
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.
Does heat travel from cold objects to hot objects?
No, heat naturally flows from hot objects to cold objects. This is based on the second law of thermodynamics, which states that heat always moves in the direction that increases the entropy of a system.
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.
In what direction does heat flow on its own spontaneously?
Heat flows spontaneously from a region of higher temperature to a region of lower temperature. This is known as the second law of thermodynamics, which states that heat always naturally flows from hot to cold in order to reach thermal equilibrium.
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?
When a cold object is touched, heat energy flows from the person's hand to the object. This is because heat always flows from the higher temperature (hand) to the lower temperature (object) in order to reach equilibrium. The sensation of coldness is due to the loss of heat energy from the hand to the colder object.
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.
