Study Notes
Laws of Thermodynamics
- The laws of thermodynamics describe the behavior of three fundamental physical quantities: temperature, energy, and entropy, which characterize thermodynamic systems.
- The term "thermodynamics" comes from the Greek words "thermos" meaning "heat" and "dynamos" meaning "force".
Zeroth Law of Thermodynamics
- 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.
- This law allows us to compare the thermal energy of three distinct bodies A, B, and C.
- When two bodies with different temperatures come into contact, they exchange heat until their temperatures are equal.
First Law of Thermodynamics
- The first law states that the total amount of energy in the universe remains constant, and energy cannot be created or destroyed, only transformed or transferred from one object to another.
- This law implies that energy transformations and transfers occur all around us, but are not 100% efficient.
- Examples of energy transformations include:
- Lights converting electrical energy into radiant energy (light).
- Billiard balls transferring kinetic energy.
- Plants converting solar energy into chemical energy.
- The human body converting chemical energy from food into kinetic energy.
- In each energy transformation, some energy is lost as thermal energy, or heat.
Second Law of Thermodynamics
- The second law states that energy cannot be transformed from a less useful form to a more useful form without some energy being lost as thermal energy.
- This law highlights the importance of understanding energy efficiency and the concept of entropy.
