Term
 --- is the ability to cause a change.
Definition
 Energy
Term
 What is an example of an activity that uses a lot of energy?
Definition
 jumping
Term
 --- is the energy of moving objects.
Definition
 kinetic energy
Term
 How can you measure the average energy of motion of the matter in a glass of water?
Definition
 by using a thermometer to measure the temperature
Term
 --- --- is the energy of motion of particles.
Definition
 thermal energy
Term
 How is thermal energy trasferred through conduction?
Definition
 one piece of matter has to touch another piece of matter.
Term
 --- is a measure of the average energy of motion of the particles in matter.
Definition
 temperature
Term
 Air temperature rises when the particles in the air move ---.
Definition
 faster
Term
 If you measured the average energy of motion of the matter in a glass of water and the average energy has increased.  What can you infer has happened?
Definition
 Thermal energy was added to the water and it warmed up.
Term
 If you measure the average energy of motion of matter in the glass of water a thrid time and the average energy had decreased.  What could you infer had happened?
Definition
 Thermal energy was taken away fromt he water and it cooled off.
Term
 Does the same aount of water take up the most space as ice, as liquid water, or as water vapor?  Why?
Definition
 The same amount of water takes up the most space as water vapor.  Water patricles move fastest when they are in the form of vapor, so there is more space around them.
Term
 Would an all-metal barn be as warm in the winter and as cool in the summer as an all-wood barn?  Why or why not?
Definition
 A barn made of metal wold not be as warm in the winter or as cool in the summer as one made from wood.  Metal is a good conductor, so the metal barn would conduct more heat from the inside to the outside in the winter and from the outside to the inside in the summer than the wood barn.
Term
 What type of clothing should you wear to stay warm in cold temperature?  How does it help?
Definition
 Closthes that are good insulators are best to wear in the winter.  They work by blocking the amount of heat that escapes from your clothing.
Term
 The energy given off by the sun is called --- ---.
Definition
 solar energy
Term
 The sun transfers bundles of energy that move through matter and space.  Those bundles are known as ---.
Definition
Term
 Bundles of energy that transfer heat are called --- ---.
Definition
Term
 You can check the --- in the morning when you wonder how warm it is outside.
Definition
 temperature
Term
 All movement of particles requires --- .
Definition
 energy
Term
 The energy of the motion of particles in matter is called --- ---.
Definition
 thermal energy
Term
 The transfer of thermal energy by particles of matter bumping into each other is called ---.
Definition
 conduction
Term
 --- is the transfer of thermal energy from one piece of matter to another.
Definition
 heat
Term
 The energy transfer by hot particles moving in a liquid or gas is ---.
Definition
 convection
Term
 Any material that can burn is a ---.
Definition
 fuel
Term
 Air temperature rises when the particles in the air ---
Definition
 move faster
Term
 The particles in water move fastest when the water is ---.
Definition
 boiling
Term
 The particles in water move slowest when the water is ---.
Definition
 frozen
Term
 When you add hot water to cold water, the cold water warms up because of --- .
Definition
 convection
Term
 --- transfers energy through infrared radiation.
Definition
 sunshine
Term
 Thermal energy can be trasferred through conduction from one piece of matter to another only if the two pieces are ---.
Definition
 touching
Term
 Solar energy heats water flowing through panels by --- ---.
