What are the three states of matter?

Solid, Liquid, Gas


100
State the Law of Conservation of Energy

Energy can not be created or destroyed, only transformed

100

This type of wave can be compared to the humps on a camel.

transverse

100

What is the highest point or peak of a wave called?

Crest

200

Heat transfer through direct contact is called....

Conduction


200

What is kinetic energy?

energy due to motion 

200

How does potential energy change as a bike goes down a hill?

The potential energy decreases as it goes closer to the ground

200

In a transverse wave, the particles move _______________ to the direction of the wave

perpendicular

200

Amplitude is the height from the ___________ to the __________ or _________

middle, crest, trough

300

A lava lamp's moving fluid is due to....

Convection

300

As temperature decreases, the kinetic energy ___________

decreases

300

Name the energy transformation of a toaster

electrical -> thermal

300

On a longitudinal wave, there are compressions and ______________

rarefactions

300
High frequency = ___________ wavelength

short

400

Explain why a hot air balloon works.

Hot air rises, so it fills up the balloon and eventually the whole balloon rises
400

Which state of matter has the highest kinetic energy?

Gas

400

Name the 4 types of potential energy

1) chemical 2) elastic 3) nuclear 4) gravitational

400
What are the main types of waves for both transverse and longitudinal waves?

transverse- light waves

longitudinal- sound waves

400

Which type of EM wave is the least dangerous and why?

Radio waves, has the lowest frequency 

500

Provide an example and explain how it has all 3 types of heat transfer

1) A hot cup of coffee

2) A water kettle on the stove

3) A heater for the house

500

Describe all three states of matter and their motions. (+100 points if your whole team does the movements)

Solids - vibrate in place

Liquids- flowing

Gases- moving very fast

500

Name the energy transformation of "A battery powers a phone that chimes when turned on"

chemical -> electrical -> sound

500

Sound waves can not travel in space, but light waves can... Why?

light waves are transverse, so they do not need a medium

500

Name all of the types of EM waves in order from lowest to highest frequency

1) radio 2) microwaves 3) infrared 4) visible 5) ultraviolet 6) X-rays 7) gamma
