Who was Dmitri Mendeleev?
The distance an object travels plus the direction from the starting point.
What is displacement?
Name the two general types of energy.
What is kinetic and potential?
The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that radiates from Earth.
What is the Greenhouse Effect?

Movement in gases and liquids that spreads out particles.
What is diffusion?
An indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave.
What is pitch?
Name two of the four types of friction.

What is a mole?
The ratio of a substance's mass to its volume.
What is Density?
A physical measurement that contains only magnitude (number) and does not contain directional information.
What is scalar quantity?
