An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.
What is atom
100
increase in the rate or speed of something.
What is Acceleration
100
the energy needed to raise the temperature of 1 gram of water through 1 °C (now usually defined as 4.1868 joules).
What is Calorie
100
CHANGING STATES. All matter exists as solids, liquids, or gases. ... Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid).
What is Change of state
100
a variable (often denoted by y ) whose value depends on that of another.
What is Dependent Variable
200
The electron is a subatomic particle, symbol e− or β− , with a negative elementary electric charge.
What is Electron
200
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
What is Air resistance
200
water that collects as droplets on a cold surface when humid air is in contact with it.
What is Condensation
200
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
What is Chemical change
200
a variable (often denoted by x ) whose variation does not depend on that of another.
What is Independent variable
300
a part or aspect of something abstract, especially one that is essential or characteristic.
What is Element
300
the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
What is Amplitude
300
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
What is Conduction
300
a roughly circular line, route, or movement that starts and finishes at the same place.
What is Circuit
300
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
What is Experiment
400
not helping or supporting either side in a conflict, disagreement, etc.; impartial.
What is Neutral
400
a comb or tuft of feathers, fur, or skin on the head of a bird or other animal.
What is Crest
400
a principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
What is Conservation of energy
400
a thing that is composed of two or more separate elements; a mixture.
What is Compound
400
the action of investigating something or someone; formal or systematic examination or research.
What is Investigation
500
Protons and neutrons, each with mass approximately one atomic mass unit, constitute the nucleus of an atom, and they are collectively referred to as nucleons.
What is Neutron
500
the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
What is Diffraction
500
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
What is Convection
500
a measure of the amount of information on a storage medium (tape or disk). For magnetic tape it is the amount of information recorded per unit length of tape (bits per inch or millimeter); for a disk, a fixed number of bits per sector, sectors per track, and tracks per disk.
What is Density
500
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
