1st Law Of Thermodynamics

Mind Map: 1st Law of Thermodynamics

Central Idea: 1st Law of Thermodynamics

  • The 1st Law of Thermodynamics states that energy cannot be created or destroyed, only transferred or transformed.

Main Branches:

  1. Definition

  2. Equation

  3. Applications

Sub-branches:

1. Definition

  • Energy: The capacity to do work or produce heat.

  • System: A specific region under study.

  • Surroundings: Everything outside the system.

  • Internal Energy: The sum of all the microscopic forms of energy within a system.

2. Equation

  • ΔU = Q - W

    • ΔU: Change in internal energy of the system

    • Q: Heat added to the system

    • W: Work done by the system

3. Applications

  • Heat Engines

    • Conversion of heat energy into mechanical work.

  • Refrigerators

    • Transfer of heat from a low-temperature region to a high-temperature region.

  • Chemical Reactions

    • Energy changes during chemical reactions.

Conclusion

  • The 1st Law of Thermodynamics is a fundamental principle that governs the conservation of energy in various systems and processes. Understanding this law helps in analyzing and predicting energy transfers and transformations.
