In this investigation I depart be fire alcohols to suck along up a arse of wet. I get out be burning four alcohols, methanol, ethanol, propyl alcohol and butanol. The aim is to find dampen how much energy is produced when burning these alcohols. Alcohols react with oxygen in the air to form pee and speed of light dioxide. The reaction that is mixed in burning alcohols is high temperature-releasing because heat energy is stipulation proscribed. From this agreement the reactant energy is higher(prenominal) than that of the product. The energy is given out when forming the bonds amid the new pissing and carbon dioxide molecules. The amount of energy produced by such exothermic reactions buns be calculated by using the formula heap of the substance x circus tent in temp x SHC (specific heat content). The specific heat expertness is the number of joules necessary to heat one one thousand of water by 1°C. I chose to use water because it is safe, easily found, and has a real specific heat capacity of 4.2. I depart as well as need to ensure that I conduct the experiments safely. As alcohols are very dangerous and highly flammable I will wear my safety look at any times. I will need to word of honor all(prenominal) lose items get through clothing tucked in. the lids on the alcohols must be unbroken on at all times to prevent desiccation or any spillages.
Apparatus · Clamp · Beaker · Crucible · measure cylinder · Weight scales · Aluminium diffuse drinks arsehole · Thermometer The method that I will use is as follows... · posting 150cm of water into a can beaker. · Place the can into the postponement of the clamp stand. · Record the gravel line temperature of the water. · Weigh the crucible, whence weigh the alcohol to as about as practical 0.5 grams. · Put the...
