When two bodies at different temperatures are placed in thermal contac...
Introduction:
When two bodies at different temperatures are placed in thermal contact with each other, heat flows from the body at a higher temperature to the body at a lower temperature until both bodies reach the same temperature. This is known as thermal equilibrium. In this process, the heat gained by one body is equal to the heat lost by the other body.
Explanation:
When two bodies at different temperatures are brought into contact, heat flows naturally from the body at a higher temperature to the body at a lower temperature. This occurs due to the difference in thermal energy between the two bodies. The heat transfer continues until both bodies reach thermal equilibrium, where their temperatures are equal.
Heat transfer:
Heat transfer occurs in three ways: conduction, convection, and radiation. However, in this scenario, we assume that there is no loss of heat to the surroundings, which means that heat transfer occurs solely through conduction between the two bodies.
The First Law of Thermodynamics:
The First Law of Thermodynamics states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system. In this case, there is no work done, so the change in internal energy is equal to the heat transferred.
Heat gained and heat lost:
When the two bodies are in thermal contact, the heat gained by the hotter body is equal to the heat lost by the colder body. This is because heat is transferred from the body at a higher temperature to the body at a lower temperature until both bodies reach the same temperature.
Conclusion:
In conclusion, when two bodies at different temperatures are placed in thermal contact, heat flows from the body at a higher temperature to the body at a lower temperature until both bodies reach thermal equilibrium. In this process, the heat gained by the hotter body is equal to the heat lost by the colder body.
When two bodies at different temperatures are placed in thermal contact with each other, heat flows from the body at a higher temperature to the body at a lower temperature until both bodies reach the same temperature. This is known as thermal equilibrium. In this process, the heat gained by one body is equal to the heat lost by the other body.
