What is Trough
100
unit of energy; the amount of heat needed to raise one gram of water one degree Celsius at standard atmospheric pressure.
What is Calorie
100
the bouncing off or turning back of light, sound, or heat from a surface.
What is Reflection
100
a mixture of two or more substances uniformly dispersed throughout a single phase.
What is a Solution
200
a force of attraction between two masses.
What is Gravitation
200
the number of cycles or waves per unit time.
What is Frequency
200
the process of changing from a gas (i.e., water vapor) to a liquid (i.e., dew); the act of making more dense or compact.
What is Condensation.
200
a change in direction of a wave that occurs as it passes from one medium to another of different density.
What is Refraction
200
a type of simple machine that consist of an inclined plane used to separate two objects.
What is a Wedge
300
the property of an object, due to its mass, that causes it to resist any change in its motion unless overcome by a force.
What is Inertia
300
the peak or highest point on a wave.
What is Crest
300
the transmission of heat through a medium and without the motion of the medium.
What is Conduction.
300
a type of simple machine that consist of an inclined plane wrapped around a cylinder.
What is a Screw
300
a type of simple machine; a slanted surface that makes it easier to move a mass from a lower to a higher point.
What is a Inclined plane
400
the distance between crest of a wave.
What is Wavelength
400
in any periodic function (e.g., a wave) the maximum absolute variation of the function.
What is Amplitude
400
a fundamental principle stating energy cannot be created nor destroyed but only changed from one form to another.
What is Conservation of energy.
400
one of the fundamental states of matter with a definite volume but no definite shape.
What is a Liquid
400
the pivot point of a lever.
What is a Fulcrum
500
the change in direction of a wave caused by passing by an obstacle or traveling through an opening.
What is Diffraction
500
force of air on moving objects.
What is Air resistance
500
heat transfer in a gas or liquid by the circulation of currents from one region to another.
What is Convection
500
having a definite shape and a definite volume; one of the fundamental states of matter.
What is Solid
500
one of the fundamental states of matter in which molecules do not have fixed volume or shape.
