|---|---|---|---|---|---|
| What is energy? | The capacity to do work OR transfer heat
🗑
|
||||
| What are the two major types of energy? | Kinetic and potential
🗑
|
||||
| Moving matter has kinetic energy because... | It has mass and velocity
🗑
|
||||
| Wind, flowing water, and electricity are examples of which type of energy? | Kinetic
🗑
|
||||
| Heat is... | The total kinetic energy of all moving atoms, ions, or molecules in a given substance
🗑
|
||||
| Heat flows from warm to... | Cool
🗑
|
||||
| What are the three methods that heat can be transferred? | Radiation, conduction, and convection
🗑
|
||||
| Electromagnetic radiation occurs when... | There are changes in electric and magnetic fields
🗑
|
||||
| Different forms of electromagnetic radiation have different | Wavelengths and energy content
🗑
|
||||
| Gamma rays, x-rays, and UV radiation have | Short wavelengths and high energy content
🗑
|
||||
| Visible light and infrared have | Long wavelengths and low energy content
🗑
|
||||
| Which type of electromagnetic radiation makes up most of the spectrum emitted by the sun? | Visible light
🗑
|
||||
| An unlit match, rock held in your hand, chemical energy stored in gasoline molecules, and nuclear energy in the nuclei of atoms are examples of... | Potential energy
🗑
|
||||
| What is an example of potential energy changing to kinetic energy? | Ex: potential energy in molecules of carbohydrates you eat change to kinetic when your body uses it to move
🗑
|
||||
| High temperature heat, nuclear fission, concentrated sunlight, high-velocity wind, and energy released from burning natural gas, gasoline, or coal, are examples of high quality or low quality energy? | High quality
🗑
|
||||
| Heat dispersed in the atmosphere or ocean is an example of high quality or low quality energy? | Low quality
🗑
|
||||
| Thermodynamics is the study of... | Energy transformations
🗑
|
||||
| The first law of thermodynamics tells us that | Energy cannot be created or destroyed; energy input=output
🗑
|
||||
| Energy consumption means | Converting energy from one form to another
🗑
|
||||
| If you fill a car’s tank with gasoline and drive around or use a flash- light battery until it is dead, you lose | Energy quality
🗑
|
||||
| The second law of thermodynamics tells us that | When energy changes from one form to another, we always end up with lower-quality or less usable energy than we started with
🗑
|
||||
| As a result of energy losing quality as it is converted... | We can never recycle or reuse high-quality energy to perform useful work
🗑
|
||||
| Energy efficiency is | a measure of how much useful work is accomplished by a particular input of energy into a system
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
