True or False, all metals conduct heat at the same speed.
What is False?

This is what happened when we added food coloring to hot water and to cold water.
What is the excited hot water molecules spread the food coloring faster than the cold water molecules.
200
This is an example of nuclear energy.
What is an atomic bomb or nuclear power plant?
200
This is the energy of motion.
What is kinetic energy?
200
These are two examples of heat energy.
What are a heater, a candle, the sun, etc.
200
This is the definition of conduction.
What is the transfer of heat energy through direct contact; for example, through a solid?
200
This is the definition of energy.
What is the ability to move or do work?
300
These are two examples of electrical energy.
What are electrical appliances, power lines, lightning, etc.
300
This is stored energy.
What is potential energy?
300
True or false, most solid, liquid and gas molecules expand when heated.
What is true?
300
This is the definition of convection.
What is the transfer of heat energy through the movement of a liquid or a gas?
300
This is the experiment we completed to show heated air molecules and how it proved how air molecules act when heated.
What is heating the balloon over the candle. The air molecules in the glass expanded, filling the balloon with gas.
400
These are two examples of chemical energy.
What is any chemical reaction (like baking soda and vinegar), food, etc?
400
If a balloon is blown up completely, it has potential energy. This is how you would transfer that energy into kinetic energy.
What is letting go of the balloon so that it is free to move?
400
This is how to inflate a balloon with a glass bottle and a heat source.
What is connect the balloon to the glass bottle, then heat up the glass bottle. The air molecules in the bottle will heat up and expand, going into the balloon and inflating it?
400
This is how solid molecules transfer energy.
What is the molecules in a solid collide and transfer the heat energy?
400
This is the difference between a calorie and a Calorie.
What is a calorie is the amount of energy required to raise 1 gram of water 1 degree celsius. A Calorie (or kilocalorie) is 1,000 calories.
500
These are the seven types of energy.
What is Sound, Light, Heat, Electrical, Nuclear, Mechanical, and Chemical?
500
These are three ways to store potential energy.
What are stretching, twisting, lifting, compressing, etc.
500
This is why heat is a form of energy.
What is because heat energy gives substances the ability to move.
500
This type of metal conducted heat energy the fastest in our experiment.
What is Copper.
500
This is how the experiment with the metal rods showed conduction.
What is the heat energy given off by the candle heated the metal rods and melted the wax at the end of the rod.
