What happens when there is a temperature difference between tow objects?

Wiki User

If they are in close contact, the hot object transfers heat to the cold object until both objects are equal in temperature. After which the temperature loss is reduced at the same rate until both objects have cooled to ambient temperature (the temperature of the surrounding air). If they are not in close contact, then most of the heat is dispersed into the air.

If there is contact between the objects then heat will travel from the hotter object to the other one. If there is no contact, then the answer depends on the temperature of the two objects relative to their environment.

Nothing need happen. There is a temperature difference between the inside of my fridge and my oven. But there is no significant thermal activity.

If those two objects are in contact with each other, they will come to thermal equilibrium, at a temperature some place between the original temperature of the two objects. The actual final temperature will depend on the specific heat capacity of each object, the mass of each object and the temperature of each object.

Heat is the amount of energy transferred between objects where a difference in temperature is present. So in that sense, heat is related to temperature differences, but is not the same. The temperature difference is caused by the difference in the avg. speed of particles between the two objects.

Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.

No. If the two objects are at temperature equilibrium, there is no heat difference between them and thus no net flow.

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.

It's not. A difference in temperature is required in order to drive the transfer of heat.

Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).

Newton's law of cooling applies to objects that are both heating and cooling. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings.

Temperature is a measure of the amount of heat energy an object has.As per the second law of thermodynamics, heat flows from hotter objects to colder objects. The bigger the difference in temperature, the more heat flows.

The temperature of the object will rise because of the heat.

The molecules which make up the objects move more vigorously.

its temperature is increased and if temperature supplied continously phase change can be changed

A question about "the difference between" requires two objects!

The distance between objects and the different is 0. The distance between the mass and an object is 1.

Raising the temperature the density is lowered.

When both objects have the same temperature. &infin;

when the temperature of both object (near or touching with each other) is different. the larger the temperature difference, the more thermal energy is transfered; from the object with higher temperature to the one with lower temperature.

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