Of or pertaining to one of the poles of the earth, or of a sphere; situated near, or proceeding from, one of the poles; as, polar regions; polar seas; polar winds.
Of or pertaining to the magnetic pole, or to the point to which the magnetic needle is directed.
The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line. If the given point lies within the curve so that the two tangents become imaginary, there is still a real polar line which does not meet the curve, but which possesses other properties of the polar. Thus the focus and directrix are pole and polar. There are also poles and polar curves to curves of higher degree than the second, and poles and polar planes to surfaces of the second degree.
Descriptive of molecules where the atoms and their electrons and nuclei are arranged so that one end of the molecule has a positive electrical charge and the other end of the molecule has a negative electrical charge. The greater the distance between the two charged ends, the higher the polarity. Polar molecules ionize in solution and impart electrical conductivity.
The uneven distribution of postive and negative charges in small molecules, resulting in an electric dipole moment.
describing a molecule or radical that has, or is capable of developing, electrical charges. Polar molecules ionize in solution and impart conductivity.
A dipole is a pair of electric charges or magnetic poles of equal magnitude but opposite polarity (positive and negative) separated by a small distance. Polarized (polar) molecules possess this electromagnetic quality.
Used to describe compounds that have a dipole moment because they consist of molecules that have negative and positive poles.
Pertaining to an orbit that is inclined approximately 90 degrees to the equator. The satellite will thus pass over the two poles as it orbits. Used by satellites that require observation of the poles or complete global coverage, such as imaging and weather satellites. [Return
having electrical poles, or regions of positive and negative charge, as in a polar molecule.
Located at or near the earth's North or South pole.
Expressed in terms of distance (from a point called the pole) and angle (with a ray as the initial side of the angle).
Referring to a molecule or structure with a net electric charge or asymmetric distribution of positive and negative charges. Polar molecules are usually soluble in water.
located at or near or coming from the earth's poles; "polar diameter"; "polar zone"; "a polar air mass"; "Antarctica is the only polar continent"
of or existing at or near a geographical pole or within the Arctic or Antarctic Circles; "polar regions"
a molecule that likes water.
Having to do with, or characterized by possessing, oppositely charged electric poles.
a characteristic of a molecule that has a greater electron density at one end than the other
Description of a satellite or orbitpassing overthe poles. The NOAA satellites used th Argos system are on polar orbits.
A compound whose molecules have an unequal distribution of electrical charge so that one part of the molecule is positively charged and another part is negatively charged. Water is a polar compound, as are most compounds soluble in water.
Characterized by a positive or negative electrical charge. Polar substances like benzene tend to dissolve in water, while non-polar substances such as pesticides tend to adsorb to soil particles.
Of the area around the poles.
where a molecule or ion exhibits a slight positive charge to one end and slight negative charge to the other. Polarity is caused by an uneven distribution of electrons.
Relating to the regions near the poles.
Some molecules, such as water, have areas of both positive charge and negative charge. Such molecules are said to be polar due to their unequal distribution of electrons.
To do with the regions of the north and or south poles of the planet. The poles are cold, icy regions, a polar climate is a cold climate, with average temperatures less than 10°C (50°F).
the regions of the earth that surround the north and south poles, from the north pole to 60 degrees north and from the south pole to 60 degrees south.
Exhibiting polarity: a molecule with opposite charges.
Descriptive of a molecule in which the positive and negative electrical charges are permanently separated, as opposed to nonpolar molecules in which the charges coincide. Polar molecules ionize in solution and impart electrical conductivity.
The opposition between two poles, such as between negatively and positively charged poles or between “good†and “badâ€, “yes†and “noâ€. Polar thinking is thinking in black and white instead of allowing a full spectrum of color.
A property of molecules in which one side of the molecule has a slight negative charge while the other side of the molecule has a slight positive charge.
Of the areas around the poles.
At one end or pole of the cell (e.g., a flagellum, spore inclusion, germ tube, etc.). ()
