The link between the number of carbon atoms in a fuel with the amount of energy it releases :: GCSE Chemistry Coursework Investigation

The link between the number of speed of light atoms in a fuel with the amount of pushing it releasesAlcohols generally belong to compounds whose molecules are based onchains of carbon atoms. They usually contain atomic number 53 oxygen atom, which isjoined to a carbon atom by a singular bandage. This makes them differentto other compounds. The oxygen atom is joined to the henry atom aswell as the carbon atom, which makes the oxygen a better of a hydroxylgroup. These atoms are generally a part of a hydrocarbon chain. Thesealcohols can take away water from the body, in which a hydrocarbonchain has replaced a hydrogen atom. Alcohols set out a general social organisationof CnH2n+1OHThe aim of this investigation is to see the link between the numbersof carbon atom in a fuel with the amount of energy it releases. in that respectwould be a diversity in the amount of energy given over off that is gettinggreater, the more carbon atoms in the fuel, the more thither are morebonds to be broken and formed, thus producing more energy. In achemical reaction, bonds in the reactant molecule are broken and peeledones are formed. Atoms are rearranged. Energy has to be adjust in to fragment bonds, and energy is given out when bonds are formed. When thetotal energy put in is greater than the energy put out, the substancecools down (it is endothermic). This is expressed as +ve (deltapositive). If the total energy put in is less than the energy created,then the substance warms up (it is exothermic). This is expressed as -ve (delta negative).I go forth investigate eight different alcohols using an alcohol or pumpburner, to measure the energy change during burning them by measuringthe change in temperature of some water held by a container. Thiscontainer must have a value of specific heat capacity so I couldcalculate heat transferred to it as well. Probably the most conductivecontainer lendable for use in the classroom is a calorimeter. As wellas not wasting energy i n the heating of the container, I could aliketry to stop heat from escaping the top and edges of the container bycovering it with a fitting lid. I will try to prevent the wind fromblowing the flames to a different direction so all the windows must beshut. supposalMore energy is released as more bonds are formed, below is the hear ofapproximate energy required to break and form all bond involved inburning alcoholsTYPE OF BOND ENERGY postulate TO BREAK THE BOND (j)
