Science test Flashcards
What was the attempt of the experiments performed by the Large Collider
produce more energetic particle collisions
Sweetened tea is an example of what
Mixtures
Boiling is a form of what
Vaporization
What tool should you use to find the weight of an object
A scale
Liters, cubic inches, quarts, and millimeters are all measures of what
volume
Coal is formed from deep layers of plant material that were under a lot of pressure and over time became rock-like. What type of force is this an example
Compression
What force is responsible for the grinding and wearing away of rock as a glacier moves over it
friction
Which force is significant in producing a snow avalanche
Gravity
The force exerted by stalactite on the roof of the cave where it hangs is an example of what
Tension
What force is probably the most important to a eologist
Gravity
What is operationally defined as the ability to do work
energy
What must an object be doing in order to have kinetic energy
Moving
In order for an objet to have potential energy, what must it have
A force
What type of energy does the sun release (there may be more than 1)
Thermal energy, light energy, and nuclear energy
Heat is defined of the flow of this type of energy from a hot place to a cooloer place
Thermal energy
These types of sounds are caused by vibrations that are too slow for the human ear to detect
Infrasonic sounds
what particles are found in an atom
Protons and neutrons
Water is an example of this
A compound
Dissolving, polishing, and evaporation are all an example of this type of change
Physical change
Lightning striking a spruce tree and starting a fire is an example of this type of change
Chemical changes
According to this theory, the days of Creation were not literal 24 hour periods.
Day-Age Theory
If you measuredan object and found it contained 38 g of matter, you have determined its what
mass
This is operationally defined as a push or a pull
A force
Your weight is directly linked to the field force known as this
Gravity
If a force is applied to an object in the same direction as it moves through a distance, this has been preformed
Work
This term is used to describe the height of a wave
Amplitude sounds
The surface of a pong becomes solid enough to hold skaters in the winter
Freezing
Butter liquifies when put in a hot pan
Melting
Droplets of water form on the outside of a chilled drink
Condensation
Gasoline disappears from an open can left in the sun
Vaporization
Ice cubes shrink while in the freezer
Sublimation
It may be ultrasonic or infrasonic
Sound energy
It is released when an atom is split
Nuclear energy
It is produced by any source of heating
Thermal energy
It may be ultraviolet or other invisible forms
Light energy
The ability to do work with electrical charges
Electrical energy
It results from moving charges that attract or repel
Magnetic energy
It may become another type of energy during a chemical charge
Chemical energy
A neutral atom becomes this when it gains or loses one or more electrons.
Ion
In fission, an atom’s nucleus splits into two smaller what?
Nuclei
This theory cannot give a good explanation for the existence of galaxies
Big bang theory
This indirectly measures how fast a substance’s particles are moving
Thermometers
What type of changes causes one pure substance to become one or more different pure substances
Chemical change
Molten steel becomes this at its boiling point
Liquid or molten
In this state, particles move so fast and collide so hard that they break apart and become electrically charged
Plasma state
Evaporation is a type of this
Vaporization
Your mass would be this (more or less) on the moon than on the earth
Stays the same
All forces act in what
Pairs
Physicists have not been able to find this, but are hoping the Large Hadron Collider will produce the super massive particle that make this
Dark Matter
Potential energy can be converted into this kind of energy
Kinetic energy
Matter and enegy can neither be ________ or __________
Created; Destroyed
In what state of matter, do the particles become electrially charged
Plasma
What is a substance’s state of matter most directly affected by
Temperature
Infrared is what type of energy
Light Energy
Matter is defined as anything that does what
occupies space
Solid aluminum is what kind of substance
pure substance
The atomic number of an element tells you how many of these are in its nucleus
Protons
