What is the Law of Conservation of Energy in thermodynamics?
Energy can neither be created nor destroyed, only transformed and transferred.
Explain the Zeroth Law of Thermodynamics.
If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
What does the First Law of Thermodynamics state?
The change in a system's internal energy is equal to the difference between the heat absorbed and the non-PV work done on it.
Define the Second Law of Thermodynamics.
Entropy, a measure of disorder, always increases in a closed system unless a reversible process occurs.
What is the difference between Classical and Statistical Thermodynamics?
Classical Thermodynamics deals with macroscopic systems, while Statistical Thermodynamics derives thermodynamic behavior from the probabilistic motion of microscopic particles.
Study Notes
Thermodynamics: The Study of Energy and Entropy
Thermodynamics, a fundamental branch of physics, investigates the relationships between energy, heat, and work—especially as they relate to the behavior of systems undergoing changes in their internal energy. This discipline is essential for understanding the natural world, from the inner workings of a refrigerator to the vastness of the cosmos.
The Laws of Thermodynamics
Thermodynamics is grounded in four fundamental laws:
- Law of Conservation of Energy: Energy can neither be created nor destroyed, only transformed and transferred.
- Zeroth Law of Thermodynamics: If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other.
- First Law of Thermodynamics (Law of Conservation of Energy): The change in a system's internal energy is equal to the difference between the heat absorbed and the non-PV work done on it.
- Second Law of Thermodynamics: Entropy, a measure of disorder, always increases in a closed system unless a reversible process occurs.
Types of Thermodynamics
- Classical Thermodynamics: Deals with macroscopic systems and their interactions, such as gases, liquids, and solids.
- Statistical Thermodynamics: Derives thermodynamic behavior from the probabilistic motion of microscopic particles.
- Chemical Thermodynamics: Focuses on the relationships between temperature, pressure, and the energy changes that occur during chemical processes and reactions.
- Biological Thermodynamics: Examines the thermodynamic aspects of biological systems, including living organisms and ecosystems.
- Relativistic Thermodynamics: Applies special and general relativity to thermodynamics, considering mass, energy, and momentum as interchangeable quantities.
