Thermal energy is transferred by these three common methods.
What are conduction, convection and radiation. (conduction - touching, like a pot on the stove; convection - a circulation of hot and cool air, like in an oven; radiation - heat "radiating" out of something, like when you put your hand near a hot tea pot and feel the heat "radiating" out)
100
Light waves are transverse waves. Visible light is only a small portion of the electromagnetic spectrum. They are found in this range of wavelength.
What is between 400 and 600 nanometers. (see the electromagnetic spectrum on the reference tables)
100
Rubbing two objects together to generate static electricity.
What is friction?
100
This describes an alpha particle.
What is a positively charged particle? (It is a helium atom with no electrons, so it has 2 protons and 2 neutrons, giving it a positive 2 charge).
100
Two objects that are attracted must have these types of charges.
What is opposite? (+ is attracted to -)
200
The law of conservation of energy.
What is energy is neither created nor destroyed. (however, it does change forms)
200
This is the definition of wavelength.
What is the distance between two identical points on a wave, such as crest to crest or trough to trough?
200
Touching an object after sliding your socks across the carpet to transfer charge.
What is conduction?
200
Nuclear reactors use this type of reaction to split large unstable atoms and produce energy.
What is fission?
200
This is why oil does not dissolve in water.
What is polarity. (Water is polar, oil is not. Remember, "like dissolves like".)
300
Heat energy moves this way.
What is from hot to cold.
300
These types of waves include sound waves.
What are longitudinal or compressed waves?
300
An example of this is when electrons slow down as they move through a circuit.
What is resistance? (the longer the wire is, the farther the electrons have to travel, the more resistance)
300
The time it takes for half of a radioactive substance to go through decay.
What is the half-life?
300
These are the six phase changes. Include what the change actually is. (Hint: Freezing is liquid to solid; now you only have to come up with 5 more!)
What is 1)freezing- liquid to solid; 2)melting- solid to liquid; 3)vaporization- liquid to gas; 4)condensation- gas to liquid; 5)sublimation- solid to gas; 6)deposition- gas to solid.
400
The unit for energy.
What is joules?
400
In sound waves, ________ determines the pitch and ________ determines the volume of a wave.
What are frequency and amplitude?
400
This type of circuit includes more than one loop with circuit elements on each path, therefore, if one component fails, the others still work.
What is a parallel circuit?
400
This is one of the largest (and most controversial) issues with nuclear power plants.
What is waste storage? (Where to store it until it is safe to move & then, where to put it for long term storage?)
400
Styrofoam is not a good conductor of heat or electricity; instead, it is considered to be one of these.
What is an insulator?
500
Energy is _____.
What is the ability to do work?
500
Frequency and wavelength are __________ related.
What is inversely? (This means that as one goes up, the other goes down. Waves with a high frequency have a small wavelength & waves with a low frequency have a large wavelength.)
500
Electrical charge generated when a charged object is brought near a neutral object.
What is induction?
500
This takes place in the sun and other stars and produces more energy than other nuclear reactions.
What is fusion? (Fusion is the combining of two small atoms.)
500
Compounds that are held together by covalent bonds do this with valence electrons.
What is share? (Co = share; CoVALENT = share valence electrons)
