Comparing the enthalpy changes of combustion of different alcohols

Introduction

I am going to investigate how and why the enthalpy change is affected by the molecular structure of the alcohols under conditions, which I have stated under 'Plan' below.

Sources

I have used the following sources in aid of devising my plan:

* My lecture notes.

* Salters Advanced Chemistry: Chemical Storylines

* 'Enthalpy' coursework form www.essaybank.co.uk

Equipment

I will use the following equipment:

* Copper calorimeter

* Thermometer

* Stand

* Boss

* Clamp

* 200 cm³ measuring cylinder

* Electronic balance

* Bunsen burner

* 2 Mats

* 5 Splinters

The above equipment are needed because the stand, boss and clamp will support and hold the metal calorimeter containing 200cm³ water, which it will be heated up by the burning alcohol underneath. The thermometer is used to measure temperature before and after the experiment and the electronic balance is used to weigh the alcohol before and after the experiment. Two mats will be used to keep heat loss, by heating the environment, to a minimum The
