Study Notes
Thermodynamics Overview
- Study of energy transformations and its principles.
Types of Systems
- Isolated System: Completely secluded from its environment; an example is liquid in a thermos, which retains temperature without interaction.
- Open System: Allows both energy and matter to flow in and out of the system, interacting with the surroundings.
First Law of Thermodynamics
- Known as the Conservation of Energy principle.
- Energy can be transferred and transformed; however, it cannot be created or destroyed.
- Asserts that the total energy of the universe remains constant over time.
Second Law of Thermodynamics
- States that every energy transfer or transformation leads to an increase in the entropy, or disorder, of the universe.
- Not all energy can be utilized; during transformations, some energy is often dissipated, primarily as heat, making it unusable.
