Descriptive:Answer

1. Existence an elements in more than one from naturally is thermal as allotropy and different forms are known as allotropes Ex: carbon as Diamond, Graphite & Fullerenes.
2. The melting point of Methane in very low hence cannot be liquefied easily, Hence its transportation for and distribution for and distribution for house hold activates will pose a previous challenge.
3. Hydrogen ban : A compound of hydrogen and carbon is known as hydrocortisone.
4. The amount of hear released per gram on complete burning (oxidation) of a fuel is known as a its calorific value.
5. When all the valency of carbon are fulfilled by single bonds it is known as saturated hydrocarbon.
   Where if there is possibility of adding from extra hydrogen in hydrocarbon it is termed as unsaturated hydrocarbon.
