Earth Science : Thermal Energy Quiz

*Theme/Title: Thermal Energy
* Description/Instructions
When an object gets warm, it is because its molecules are moving fast. The warmer an object is, the more kinetic energy its molecules have. Kinetic energy is also known as thermal energy. To tell how warm or cold an object is, one would measure its temperature. Temperature is a measure of the average kinetic energy of an object’s molecules. Substances that have high temperatures have molecules that move very fast. Temperature has no upper bound; there is no limit to how hot an object can get. However, there is a point where an object cannot get any colder. This is called absolute zero, and it has a Celsius temperature of -273 degrees. At this temperature, molecules do not have any kinetic energy because they have stopped moving. This quiz covers the basics of thermal energy. Use the above information to assist in answering the questions. Select the best answer from the choices.
