Two blocks which are at different states are brought into contact with...
It's zeroth law..which state that if two or more object comes in CONTACT with each other..than temp or heat will exchange and at last all of them having same temp...temp is exchange becz temp is a function of heat..and here we don't need to any work and becz they are in contact.so according to 1st and 2nd law thr should be a bridge in between doner and exceptor.

Zeroth law of thermodynamics:
The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law establishes the concept of temperature and provides the basis for the measurement of temperature.
Explanation:
When two blocks at different temperatures are brought into contact with each other, heat transfer occurs between them until they reach a final state of thermal equilibrium. This means that the blocks will reach a common temperature where there is no further net heat transfer between them.
Process:
1. Initially, the two blocks are at different temperatures.
2. When they are brought into contact, heat flows from the block at higher temperature to the block at lower temperature.
3. This continues until the temperature of both blocks becomes equal.
4. At this point, the heat transfer between the blocks stops and they are said to be in thermal equilibrium.
Significance:
The zeroth law of thermodynamics is important because it allows us to define and measure temperature. It states that when two systems are in thermal equilibrium, they are at the same temperature. This provides a basis for the comparison and measurement of temperature, allowing us to develop temperature scales and thermometers.
Application:
The zeroth law of thermodynamics is applied in various fields, including:
1. Temperature measurement: It helps in the calibration and use of thermometers, allowing us to measure temperature accurately.
2. Thermal management: It is used in designing and optimizing systems that involve heat transfer, such as heating and cooling systems.
3. Heat exchangers: It is used to ensure efficient heat transfer between fluids in various industrial processes.
4. Thermal comfort: It helps in understanding and maintaining comfortable conditions for humans in buildings, vehicles, and other environments.
Conclusion:
The zeroth law of thermodynamics is the correct answer for the given scenario. When two blocks at different temperatures are brought into contact, they will reach a final state of thermal equilibrium where their temperatures become equal. This concept is fundamental in the measurement and understanding of temperature.
