Energy
The internal energy present in a system due to the random kinetic energy, movement, and vibration of its atoms and molecules
What is Thermal Energy?
A form of power derived from the movement of charged particles, such as electrons, either through a conductor or stored as a result of their position
What is Electrical Energy?
This is the specific type of energy stored in the bonds of chemical compounds
What is Chemical Energy?
A form of mechanical energy produced by vibrating objects, which travels in waves through substances like air, water, or solids
What is Sound Energy?
A form of electromagnetic radiation, visible to the human eye, that travels as waves and behaves as particles
What is Light Energy?
This process involves the circular movement of fluids where warm material rises and cool material sinks
This stationary electric charge is often produced by friction, like rubbing a balloon on your hair
What is Static Electricity?
This common household item stores chemical energy and converts it into electrical to power devices
What is a Battery?
Unlike light, sound energy requires one of these to travel through
What is a medium?
Light energy travels in these, which are the fastest things in the universe
What are Waves?
This is the only form of heat transfer that can travel through empty space via electromagnetic waves
What is Radiation?
This term refers to continuous flow of electrons through a conductor
What is Electric Current?
This biological process allows plants to convert solar energy into stored chemical energy in form of glucose
What is Photosynthesis?
Because there are no molecules to vibrate, sound cannot travel through this "empty" environment
What is a Vacuum?
This term describes a material, like clear glass, that allows all light to pass through it
What is Transparent?
A sea breeze or boiling macaroni swirling in a pot are real-world examples of this specific heat transfer
What is Convection?
Metals like copper, silver, and gold are categorized as this because they allow electricity to move through them easily
What are conductors?
These three types of energy sources--coal, oil, and natural gas--store chemical energy from ancient organic matter
What are Fossil Fuels?
Sound travels fastest through this state of matter because the molecules are packed tightly together
What is a Solid?
The type of material, like frosted glass or wax paper, scatters light so you can't see clearly through it
What is Translucent?
This is the term for the transfer of thermal energy between two systems, which always moves from a higher temperature to a lower temperature
What is Heat?
This safety device "breaks" or melts when a current is too high to protect a circuit from damage
What is a Fuse?
This term describes a chemical reaction, like a campfire, that releases energy in form of heat or light
What is an Exothermic Reaction?
This is the high-pressure part of a sound wave where molecules are pushed closely together
What is a Compression?
In a vacuum, light travels at approximately this speed per second
What is 300,000 kilometers per second?
