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

The transfer of thermal energy through objects in physical contact is called conduction.

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.

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.

No,two objects at different temperature does not have the same thermal energy because both objects have different temperature .object with high temperature has more thermal energy and the object with low temperature has less thermal energy.

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.

If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.

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....

Yes.Since temperature is the average kinetic energy of all of the particles (i.e., thermal energy/mass) and thermal energy is the total, two objects of different mass and different internal energies can have the same temperature.Also, another way of looking at it:If you have two objects of the same temperature and different masses, and multiply that temperature by the masses of the objects, you will get their thermal energies, which will be different for both objects.

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.

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

When two objects are in thermal equilibrium, not heat will flow between them - which is in accord with the 2nd law of thermodynamics. This is also related to (but different from) the zeroeth law which states that if two objects are each in equilibrium with a third object, they must be in thermal equilibrium with each other.

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

1. The two objects are to be in thermal contact. This means that everything between the two objects must be a conductor. 2. There is to be a temperature difference between the two objects. One must be hotter than the other. Given these two conditions, heat will pass from the hotter to the cooler object. That is one of the fundamental laws of thermodynamics.

The thermal conductivity temperature of different objects vary from one object to another. When the two objects are placed together, there will be a change in temperature through heat conduction.

it's sort of like diffusion, the object with the higher temperature will transfer its energy through conduction to the cooler object. after long enough, they will have the same temperature.

At thermal equilibrium, two objects reach the same temperature. An object with a higher temperature transfers heat to an object with a lower temperature when they are in contact.

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

When two objects at difference temperatures touch, they both decrease or increase to result in the same temperatures so that it's at equilibrium. To change in temperature, the heat energy from the the object with the higher temperature will always flow to the object with the lower temperature. This is also the definition of heat and is not to be mistaken with temperature. Heat is the transfer of energy from an object with a higher temperature to an object with a lower temperature. Temperature is the measurement of kinetic energy of particles in an object.
