What are polar and non-polar liquids?
A polar liquid is a liquid that does not have any/much of a hydrocarbon chain and has mainly OH, NH or even C=O or C=-N groups. As you increase the carbon chain, you become less polar. Polar solvents include water, dimethylformamide, ethanol, methanol, acetonitrile to name a few. Non polar solvents include pentane, hexane, toluene, heptane to name a few.
Why are climates in the polar zones extremely cold?
The polar zones receive less direct sunlight due to the Earth's tilt, leading to lower temperatures. Additionally, the high albedo of snow and ice in these regions reflects sunlight back into space, further cooling the area. Atmospheric circulation patterns also contribute to the cold temperatures in the polar zones.
What coutries have a polar climate?
The best list is probably Canada, Norway, Sweden, Finland, United States (Alaska), and Russia which all have northern portions of their countries which have polar climates. Alternatively the list could be Canada, Norway, United States, Russia, Greenland, and Iceland.If we the Koppen climate categorization, a "Polar climate" to be one where every month has an average temperature of less than 10 °C (50 °F), then several other areas qualify.Note that Greenland, which is an autonomous constituent country within the Kingdom of Denmark has a polar climate.Northern portions of Iceland have a polar climate.The Southernmost portion of South America at Tierra del Fuego, which lies in Chile and Argentina also has a polar climate.If you include extremely high mountains, several other countries join the list including Peru and Bolivia in the Andes, and Nepal, Bhutan, and China where the Himalayas reach extreme heights.
Which compounds elute first in non polar gc column?
In a non-polar GC column, compounds with lower polarity elute first. Non-polar compounds are less attracted to the non-polar stationary phase of the column, so they move through the column faster than polar compounds.
What are the reasons for less beard?
only two reasons. 1.low testostiran 2.low vitamin
Snow on the ground prevents polar climates from gaining heat by what mechanism?
Snow on the ground reflects a significant amount of sunlight back into space, preventing the ground from absorbing heat. This results in less warming of the surface in polar climates. Additionally, snow has a high albedo, which means it is highly reflective and absorbs less solar radiation, further reducing the amount of heat absorbed by the surface.

What are the reasons for using a dog treadmill?
For active dogs who have less than active owners, a dog treadmill may be the solution. It can be especially useful for those living in climates that are not conducive to strenuous exercise.
Where was the black death more virulent?
hotter climates. in colder climates it tended to die out quickly, and spread less.
Why are desert climates less populated than other climates?
The desert is hot and dry, so why would people want to live there?
If the column is polar then what types of illution first polar or non-polar?
if the column is polar then non polar ellute first because of its less interaction with that of stationary phase.
In polar areas solar radiation strikes Earth at a?
In polar areas, solar radiation strikes Earth at a lower angle, leading to less direct sunlight and lower overall energy received per unit area. This results in colder temperatures and contributes to the formation of polar climates characterized by ice and snow.
Why are climates in the polar zones extremely cold?
The polar zones receive less direct sunlight due to the Earth's tilt, leading to lower temperatures. Additionally, the high albedo of snow and ice in these regions reflects sunlight back into space, further cooling the area. Atmospheric circulation patterns also contribute to the cold temperatures in the polar zones.
What is the difference between covalent bond that is polar and one that is not?
the polar one is less stable than the non-polar one
What is a polar bear coy?
A polar bear cub less than 1 year-old.
What compound is more polar ch3ch2ch2ch2ch2ch2ch2oh ch3ch2ch2ch2oh or ch3oh how do you know?
The compound ch3ch2ch2ch2ch2ch2ch2oh is the most polar because it has the longest carbon chain with an -OH group, which increases its polarity due to hydrogen bonding. Shorter chains like ch3ch2ch2ch2oh and ch3oh are less polar as they have shorter hydrocarbon chains.
Does polar water diluted by melting ice become less or less dense?
less denser than
