What are the physical and chemical compositions of corn cob responsible for its insulating property?
441898
Corn cob is mostly cellulose and air. It is the trapped air that is the primary insulator.

styrofoam because it is a better insulator of heat than the other materials mentioned\n\nyou do not have to be a physician to know that

The energy contained in corn is in the form of stored chemical energy (in the form of hydrocarbons), that was created by solar energy and photosynthesis of the corn plant. \n\nThe seeds of corn can be made into sugar, food, ethanol, or even burnt alone as fuel. Each of these products contains hydrocarbons that contain chemical energy that can be converted to heat energy. Some new work is being done to convert the rest of the corn plant to ethanol or other sources of energy. It was common to burn corn cobs during the depression as fuel to heat homes. Today, they may be converted to alchohol fuel for automobiles using genetically engineered yeast. Shell Global Solutions and Iogen in Canada have built a demonstration plant to create ethanol from cellulose, which could include the entire corn plant, or other plant materials like wheat straw that shows great promise for producing environmentally-friendly economic fuel.

carbon fiber.\nit comes as a soft material rolled up like cloth, then they cut it and put it around a mould. It is hardened by putting it under a vacuum, and then in a huge autoclave which cooks the material. the result is strong yet light carbon-fiber

Element = Sodiuim.  It still retains its properties even at the atomic level.\n\nCompound = NaCl (Table Salt).  It consists of two chemically bonded elements.\n\nMixture = sand and sugar.  No chemical bonding occurs.

Less dense materials are better insulators. The denser the material, the closer its atoms are together. That means the transfer of energy of one atom to the next is more effective. Thus, gases insulate better than liquids, which in turn insulate better than solids.\n\nAn interesting fact is that poor conductors of electricity are also poor heat conductors. Wood is a much better insulator than copper. The reason is that metals that conduct electricity allow free electrons to roam through the material. This enhances the transfer of energy from one area to another in the metal. Without this ability, the material--like wood..AND IN YOUR CASE RUBBER--does not conduct heat well.

The angiosperm primary cell wall (PCW) composition is Glc, Gal,Ara, Xyl, Fuc, GalA, Rha, GlcA and Man. PCW composition among angiosperms differs only in proportional\nquantity of each monosaccharide. PCWs of gramineous monocots contain more Xyl and less Gal, Ara and Fuc than those of other angiosperms.  Do not confuse this with bryophytes, which naturally contain more GalA, GlcA and Man.
