Heat energy flows form the warmer object to the cooler object, and their temperatures change toward each other, so that the difference in temperatures decreases.

In that case, heat will flow from the hotter to the colder object. This will continue until both are at the same temperature.

There is a transfer of heat energy from the object at higher temperature to the object at lower temperature, which continues until the two objects are at the same temperature as each other.

thermal energy(heat) transfer to cooler objects...............................................................................................................

Different objects may have different temperatures

No. It is an example of radiation. The heat is transferred by microwaves, which are a form of electromagnetic radiation. Conduction occurs when two objects of different temperatures are in contact or when different parts of an object have different temperatures.

If the items continue to touch they will get colder or warmer till they are the same tempature.

because when two objects are brought in contact with each other which are having different temperatures heat flow from higher to lower that is conduction takes place till the temperature of both become equal....

The object with the lower average temperature will take heat from the other object until both objects have the same temperature.

Heat will flow from the object that has the higher temperature, to the one with the lower temperature. This will continue until equilibrium is reached, i.e., both objects have the same temperature.

Heat will flow from the hooter object to the cooler object until the temperatures are equal.

Since different objects have different heat conductivity and different temperatures and heat capacities, the time can vary without limit.

Heat is thermal energy. If two objects having different temperatures are brought into contact, heat will always flow from the warmer one to the cooler one, until their temperatures are equal.

Friction acts when there is contact between two or more objects. Gravity acts on all objects with or without contact.

Heat energy will be transferred from the hotter objects to cooler objects until they are all at the same temperature.

If the contact is good, then energy (heat) will pass from the object at a higher temperature to the one at a lower temperature until the temperatures of the two bodies are equal. This precludes cases such as a burning match stick touching a flammable object and such

OK, let's see an example. Two objects of the same mass and same material (for simplicity) have temperatures of 50&Acirc;&deg; and 60&Acirc;&deg;, respectively. When heat is transferred between them, they may have temperatures of, say, 51&Acirc;&deg; and 59&Acirc;&deg;; later 52&Acirc;&deg; and 58&Acirc;&deg;, etc.; this will continue until they have the same temperature. But if they only have contact for a brief time, they will not necessarily have the same temperature - it needs a certain time for the temperatures to become equal.

Convection, flowing through a liquid or a gas, Conduction, a transfer that occurs between the contact between two objects of different temperatures, or Radiation, where heat is emitted from the surface of an object.
