Title: Investigating the Energy Content of Homologous Alcohols: From Methanol to Pentanol
Description: This document provides an in-depth investigation into the energy content of homologous alcohols, from methanol to pentanol, using a calorimetric method. It explores how the number of carbon atoms affects the energy released per gram during combustion. The research includes background information on organic molecules, combustion reactions, and calorimetry, along with detailed methodology, data analysis, and conclusions. The findings contribute to our understanding of fuel efficiency and energy density, with practical applications for fuel selection in heating, cooking, and engines.

Investigating the energy contained in different fuels
...
They are very important in
chemistry
...
But the
main part is made of carbon atoms
...
They arethe simplest organic compounds
...
They are different because of
how the carbon atoms are bonded together
...
Each compound in
the series has a repeating part, usually -CH2-
...
Alcohols are a homologous series
...
Then comes ethanol (C2H5OH), propanol (C3H7OH), and so on
...
Each of these
alcohols contains the hydroxyl functional group (-OH) bonded to a carbon atom,
which is characteristic of the alcohols series
Alcohols
Alcohols are basic things with oneor more hydroxyl (-OH) groups on a carbon atom
...
Alcohol can beused to help mix other things or to makethings burn
...
Bigger alcohols
with more carbon atoms can giveoff more energy when they burn because they have
more carbon and hydrogen that can burn
...
They happen when a
fuel, likegas or wood, mixes with air
...
When things burn, they make new things too
...
The science words for it are:
Alcohol+O2→CO2+H2O+heat
Alcohol+O2→CO2+H2O+heat
The reactions that happen when alcohol burns are called exothermic reactions
...
Theenergy comes from thebonds in the
products, like carbon dioxide and water
...
Thedifference in energy is
released d
...
They show that theproducts have
less energy than the reactants
...
This means the reactions
are exothermic
...
This shows the energy released
...
It works very well for
measuring the warmth made by fuel
...
Scientists use it to measurethe heat transfer from the
reaction
...
The reason energy content is measured per gram of fuel is to provide a basis for
comparison among different fuels
...
This metric is crucial for applications like fuel selection
for heating, cooking, and powering engines, where energy efficiency and fuel mass are
critical considerations
...
This prediction is based on the understanding that long
