States of Matter
Which state of matter has a indefinite shape and an indefinite volume?
GAS
The smallest amount of an element...
ATOM
What is the term used to describe the change from LIQUID to SOLID?
FREEZING
Which subatomic particle moves from atom to atom to make electricity? (Proton, Neutron, or Electron)
ELECTRON
If a light wave has a high amplitude (or a lot of energy) will it be bright or dull?
BRIGHT!
Which state of matter has both a definite shape and a definite volume?
SOLID
What law states that mass in a closed system is neither created nor destroyed by chemical means or physical changes?
LAW OF CONSERVATION OF MASS
What is the term used to describe the change from LIQUID to GAS?
VAPORIZATION (or EVAPORATION)
A negatively charged rod is brought towards a ball, and the ball rolled away from the rod. What was the charge of the ball?
NEGATIVE
The maximum displacement or height of a wave. (For sound waves, this affects volume).
AMPLITUDE
As a material transitions from SOLID to LIQUID, what is happening to the kinetic energy of its particles?
THEY ARE SPEEDING UP
When two atoms (same element) bond together, they form...
MOLECULES
What is the term used to describe the change from GAS to LIQUID?
CONDENSATION
In a circuit, this is the energy source that provides electric charges. They have a positive and negative side.
BATTERY
When a wave hits a surface and goes directly though the substance.
TRANSMISSION
As a material transitions from GAS to LIQUID, what is happening to the kinetic energy of the particles?
THEY ARE SLOWING DOWN.
How would you best identify a substance that consisted of two nitrogen atoms bonded to an oxygen atom? (atom, element, molecule, or compound?)
COMPOUND
What is the term used to describe the change from SOLID to GAS?
SUBLIMATION
A circuit in which all components are connected in a single pathway.
SERIES
When a wave hits a surface and bounces back in the direction it came.
REFLECTION
What is needed for a phase change to occur?
ENERGY!! (THERMAL)
Is this a compound or a pure substance?
PURE SUBSTANCE
What is the term used to describe the change from GAS to SOLID?
DEPOSITION
This component of Ohm's Law measures the amount of energy provided to the circuit by the power source.
VOLTAGE
What is the frequency of this wave?
