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.
