Study Notes
Celsius Scale
- Temperature scale where water freezes at 0°C and boils at 100°C.
- Commonly used worldwide for scientific and daily temperature measurements.
Centripetal Force
- Force that directs an object to move in a circular path.
- Essential in understanding motion in rotating systems, like planets and satellites.
Change of State
- Physical transformation of matter from one state (solid, liquid, gas) to another.
- Examples include melting, freezing, evaporation, and condensation.
Chemical Energy
- Potential energy stored in the bonds of chemical compounds.
- Released during chemical reactions; essential in biological processes and energy production.
Combustion
- Process of burning fuel to generate thermal energy.
- Involves a chemical reaction between a fuel and oxygen, producing heat and light.
Compound Machine
- Device that consists of two or more simple machines working together.
- Increases efficiency and effectiveness, e.g., bicycles and wheelbarrows.
Condensation
- Transition from gas phase to liquid phase in matter.
- Observed in processes like the formation of dew or water droplets on cold surfaces.
Conduction
- Heat transfer through direct contact of particles in matter.
- Fundamental process for temperature distribution in solids, liquids, and gases.
Conductor
- Material that allows heat to pass through it easily.
- Examples include metals like copper and aluminum, commonly used in electrical wiring.
Convection
- Heat transfer through the movement of currents within a fluid (liquid or gas).
- Crucial in atmospheric phenomena, ocean currents, and heat distribution in cooking.
