Study Guide: Light and Sound
Check-in 1: What is energy? What is thermal energy?
Vocabulary:
Energy- The ability to do work and cause a change in matter.
Thermal Energy- Heat energy
Temperature- The measure of thermal energy or how cool or warm things are.
Conduction- Process by which heat or electricity is transferred through an object.
Conductor- Materials where heat or electricity flows easily from molecule to molecule.
Insulator- Material where heat does not flow easily from molecule to molecule.
Key Concepts:
• Heat, light, and sound forces are different types of energy.
• Temperature is measured in degrees Fahrenheit and/or degrees Celsius.
• Temperature is measured using a thermometer. As heat increases, the molecules of the colored
liquid inside the thermometer expand, causing the liquid to rise.
• Examples of good conductors are iron, aluminum, copper, some other metals, and water.
• Examples of good insulators are plastic, rubber, air, wood, cork, chalk, etc.
• Molecules speed up and move farther apart when heated.
• Molecules slow down and move closer together when cooled.
• Heat moves from warmer to cooler objects
