# What happens at thermal equilibrium?

###### Wiki User

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.

Thermal equilibrium is a uniform temperature throughout a system. The equilibrium temperature is the temperature at which this happens.

To be in thermal equilibrium, it would have to have the same temperature. (It isn't.)

because the earth and the sun is not in the thermal contact with each other that is why the earth &amp; the sun is not in thermal equilibrium.

Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they must be in thermal equilibrium with each other. This law helps define the notion of temperature.

Thermal equilibrium is the subject of the Zeroth Law of Thermodynamics. Zeroth Law of Thermodynamics. The "zeroth law" states that if two systems are at the same time in thermal equilibrium with a third system, they are in thermal equilibrium with each other.

If A,B and C are three systems and A is in thermal equilibrium with B and B is in thermal equilibrium with C then according to zeroth law of thermodynamics C is in thermal equilibrium with A.

When the temperatures are the same, things are in thermal equilibrium.

No., because thermal property like conductivity, diffusivity of two material my not be same in other medium.

Equilibrium means balance or equal. Thermal equilibrium is when two systems have equal temperatures. Mechanical equilibrium is when two systems have equal pressure. In a steam engine, if you stop putting fuel into the furnace, the pressure in the boiler will drop until it reaches mechanical equilibrium with the atmospheric pressure and the water will cool and reach thermal equilibrium with the ambient temperature.

The zeroth law states that if two systems are both in thermal equilibrium with a third system, they would be in thermal equilibrium with each other if brought into thermal contact. Two systems are said to be in the relation of "thermal equilibrium" if they are linked by a wall permeable only to heat (in thermal contact), and do not change over time.

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.

Thermal equilibrium is when the temperature of a system or organism is equal to the temperature of its surroundings.

Thermal equilibrium is established by the transfer of heat energy from the hotter object to the cooler object until both objects are at the same temperature.

When thermal equilibrium is reached.

From the Wikipedia article: "The zeroth law states that if two systems are in thermal equilibrium with a third system, they are also in thermal equilibrium with each other."

No, order can't spontaneously appear in a macroscopic closed system which has reached thermal equilibrium.

When denstiy of the materials that are in contract are the same

Since hot water is less dense that cold air the hot water will rise and the cold would sink then it keeps doing this in a circular motion 'till the thermal energy reaches to thermal equilibrium.

Thermal Equilibrium is achieved when two objects reach the same temperature and exchange energy through heat. Eventually the temperature between the two objects will be equal and will stop exchanging heat. At this point, They are in a state of Thermal Equilibrium.

thermal equilibrium means 6 conditions 1- Temperature is constant 2-Electric field =0 3- Current density of free carriers equal zero

equilibrium readjusts itself and a new equilibrium is established
