Study Notes
Environment Overview
- The environment consists of physical, chemical, biological, social, economic, and cultural components that interact with and influence each other.
- Humans are part of ecosystems, which include both abiotic (non-living) and biotic (living) factors.
Ecosystem Complexity
- Abiotic factors include physical factors (e.g., temperature, sunlight) and chemical factors (e.g., pH, nutrients).
- Biotic factors refer to all living organisms within an ecosystem.
Matter and Energy
- Matter is defined as anything that has mass and occupies space.
- Energy is defined as the capacity to perform work.
Transformations of Matter and Energy
- Transformations can occur between mass and mass, mass and energy, and energy and energy.
- Each transformation typically involves the release or absorption of energy, particularly in industrial processes.
States of Matter
- Matter exists in various states based on the arrangement and energy of particles:
- Solid State: Particles vibrate but do not move freely; definite shape and volume due to strong cohesion forces.
- Liquid State: Particles are close together but can move freely; definite volume but no definite shape.
- Gaseous State: Particles move freely with no definite shape or volume due to weak cohesion forces.
Extreme States of Matter
- Plasma: A high-energy state of matter where gas is heated to the point that it loses electrons; common in stars.
- Bose-Einstein Condensate: Formed at temperatures near absolute zero, where particles behave like a single quantum entity or wave.
Key Concept Summary
- Water is unique as it can be found in all three states: solid, liquid, and gas.
- The movement of particles and energy concentration dictate the state of matter.
