Final Jeopardy
The Electromagnetic Spectrum
Final Jeopardy
What is 1/1,000,000,000 of a meter and the length of a football field?
This is the size of a wavelength of a gamma ray
and this is the size of a wavelength of a radiowave.
$200
What is matter?
This is the scientific term for “stuff”.
$400
What is an atom?
The smallest piece of matter.
$600
What is the nucleus?
The center of an atom.
$800
What is an electron?
This subatomic particle has a negative charge.
$1000
What is a molecule?
When more than one atom are joined together.
$200
What is a Bose-Einstein Condensate?
If atoms were NOT moving AT ALL.
$400
What is a liquid?
When atoms are not as tightly packed together, are able to slide past each other, and have a definite volume.
$600
What is a gas?
When atoms have no definite shape and no definite volume. They are moving fast and are
very spread out.
$800
What is 100 degrees Celsius or 212 degrees Fahrenheit?
The boiling point of water (in two different units of
measurement).
$1000
What is Absolute Zero?
The temperature at which all molecular movement stops.
$200
What is temperature?
The measurement of how much molecules are moving
in a substance.
$400
What is thermal expansion?
When molecules move farther apart when heated.
$600
What is contraction?
When molecules move closer together when cooled.
$800
What is hot gas?
Hot gas vs. cool gas. One is LESS DENSE.
$1000
What is “until they reach thermal equilibrium”?
Heat is always transferred from a hotter object to a cooler object until…..
$200
What is a gas?
This is the only state of matter than can be
compressed.
$400
What is a conductor?
Metal is an example of this, because it transfers heat well.
$600
What is an insulator?
You used a lot of these in your Thermos design,
because they do not transfer heat well.
$800
What is radiation?
An example of this type of heat transfer is how our
atmosphere gets heated from the sun.
$1000
What is the hot water at the bottom expands and becomes less dense so it rises, then at the top it cools and becomes more
dense and sinks.
This is the science behind how convection is able to heat an entire pot of water.
$200
What is the Diffusion Lab?
This lab proved that atoms and molecules are always
moving.
$400
What is that molecules move farther apart when heated, and move closer together
when cooled.
In the Hot Gas/Cool Gas Lab, we learned…..
$600
What is that liquids cannot be compressed but gasses can, so when we squeezed the
bottle the liquid compressed the gas in the dropper, making it more dense, so it sunk.
The Diving Dropper dove because….
$800
What is to reflect radiation from a hot beverage back to the beverage?
The inner lining of your thermos might be silver
because….
$1000
What is to prevent heat transfer by conduction or convection? They both
require molecules to transfer heat.
Your Thermos might have a space with some air or no air
at all in it because….
$200
What is it is a conductor and it is taking the heat from your hand very quick, so it feels
cold.
Why is the table leg so cold?
$400
What is UV radiation.
This type of radiation can cause a sunburn.
$600
What is Infrared Light?
This type of radiation is felt as heat. You give it off and
the sun gives it off!
$800
What is the Greenhouse Effect?
This is the method in which radiation from the sun is
trapped in our atmosphere. Without it, the Earth would
be too cold to live on.
$1000
What are greenhouse gasses?
These substances are making our atmosphere better and
better at trapping heat, therefore heating up our
world.
