What law of thermodynamics does this illustrates when two objects are in thermal equilibrium?

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.


When is thermal equilibrium achieved between two objects?

When both objects have the same temperature. ∞


What is it called when objects have the same temperature and the energy is no longer being transferred between two objects?

equilibrium state----- ----- ----- ----- ----- ----- ----- ----- ----- ------ ----- ----- ----- -----'Thermal Equilibrium'.


When two objects are in thermal equilibrium is there a net flow of heat between them?

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


How is thermal eqilibrium achived?

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.



What happens at thermal equilibrium?

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.


What needs to happen for thermal energy to be transferred and what needs to happen at thermal equilibrium?

You have to have two objects at different temperatures near each other, when two or more objects have the same temperature.


How can you tell two objects are in thermal equilibrium?

That's when they have the same temperature, which you can measure with a thermometer.


What is the point at which two objects that are touching reach the same temperatures?

It really depends on the atmosphere temperature around it, and the temperature of the two objects.I believe it is called thermal equilibrium.


What states that the two system which are in thermal equilibrium with a third system are in thermal equilibrium with each other?

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.


How is thermal equilibrium established?

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.


Two bodies Are in rotational equilibrium if they are at the same temperature?

They are in thermal equilibrium, not rotational equilibrium.


If two bodies are in thermal equilibrium in one frame will they be in thermal equilibrium in all frames?

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


What is thermal equlibrium-?

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.


What does thermal equilibrium mean?

It means that two (or more) objects are at the same temperature, so there is no net flow of heat energy in one direction or in the other.


What does zeroth law of thermodynamics states?

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.


Distinguish between thermal and mechanical equilibrium?

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.


What is thermal equilibrium and equilibrium temperature?

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



What is the zeroth law of thermodnamics?

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."


What is special about the entropy in thermodynamic equilibrium compared to all statesof a system?

In thermal equilibrium, and only in thermal equilibrium, entropy is constant.


Why the earth is not in thermal equilibrium with yhe sun?

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


What is the point at which the net flow of thermal energy between two objects at the same temperature is zero?

When the temperature of the two objects is equal, the Thermal Flow will stop.


Why is the earth not in thermal equilibrium with the sun?

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