During the day, the temperature of the sand in a desert rises as the sand is heated by the sun. after the sun sets, the sand cools. what happens to the heat energy in the sand as it cools?

Deserts are the regions that cover little or no vegetation and there is no rainfall. Deserts are very hot in the day time and cold during the night time. It is because during the day time the sun heats up the sand, as a result of which the sand becomes very hot increasing the temperature. This increasing temperature in the desert is also because of the absence of rainfall and vegetation cover.

Thus, the desert area is rich in heat energy during the day time. But at night, the sand releases its heat energy back into the atmosphere through infrared radiation because the dry air cannot hold the heat anymore. This release of the heat energy allows the sands to cool, thereby dropping the temperature.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
