Study Notes
Phase Changes of Matter
- Freezing: Transition from liquid to solid.
- Evaporation: Change of liquid into gas.
- Condensation: Process where gas converts back to liquid.
- Sublimation: Direct transition from solid to gas.
- Deposition: Conversion from gas directly to solid.
- Melting: Process of solid turning into liquid.
Physical vs. Chemical Changes
- Physical Change: Changes in phase or state of matter without altering composition.
- Chemical Change: Involves alteration of a substance's chemical composition.
- Thermal Decomposition: Breakdown of substances due to heat.
- Oxidation: Chemical reaction where oxygen combines with another substance.
Biological Processes
- Aerobic: Refers to processes occurring in the presence of air.
- Aerobic Respiration: Requires oxygen to produce energy from glucose, resulting in carbon dioxide.
Reproductive Systems
- Male Hormones: Testosterone is the primary male sex hormone, responsible for the development of male sexual characteristics and sperm production.
- Female Hormones: Estrogen and progesterone regulate female sexual characteristics and egg production.
- Responsibility of Hormones: These hormones influence physical changes during puberty and can lead to mood fluctuations.
Male Anatomy
- Bladder: Stores urine until it is excreted from the body.
- Prostate Gland: Plays a role in male reproductive health by producing seminal fluid.
