Investigating Whether There is a Link Between The Number of Carbon Atoms in a Fuel and the Amount of Heat Produced
Aim
The aim is to investigate if there is a link between the number of
carbon atoms in a fuel and the amount of heat produced by that fuel.
Prediction
I predict that the more carbon atoms that are in a fuel, the more heat
the fuel will generate.
Risk Assessment
There are some safety precautions that will have to be taken when the
experiment is carried out. These will be determined by the hazards
that are in the room and hazards that could occur.
These are:
Ÿ Heatproof mat
Ÿ Goggles
Ÿ Tie tucked in shirt
Ÿ Hair clipped back
Ÿ The alcohol’s are flammable so care must be taken with them
Ÿ Equipment might get hot
Ÿ There will be naked flames
Equipment used and reasons
³ Calorimeter - this is used to hold water. This is used because
it is non flammable so even when in close contacts with the fuels, it
will not burn.
³ Tripod - this is used to keep calorimeter at a safe distance
away from the fuels.
³ Heat proof mat - this is used so that the desk does not get
burned or marked when the fuels are burning.
³ Thermometer - this is used to measure the temperature of the
water, before and after the experiment.
³ Measuring cylinder - this was used to measure the 100ml of water
that was needed for the experiment.
³ Alcohols - this is used as the fuels for the experiment
³ Foil - this is used to stop heat escaping for the fuels so that
the water heats up more quickly.
³ Balances - this is used to weight the fuels before and after
To investigate the relationship between three different alkanols in terms of their carbon chain length, rate of increased temperature, and heat of combustion, in order to determine which is the most efficient at heating water to a certain temperature whilst reducing time and effects on the environment.
anyway) Note these factors affect the rate of the reaction, but not the final. amount of carbon dioxide produced). Why these factors affect it: higher temperature makes atoms move more. so they are more likely to bump into each other and react.
The investigation topic is about the fuel that makes a space rocket fire. A combustion reaction is more known as burning. Combustion isn’t always burning, but when it is, the flame causes most of the reaction ( in our case, to make our bottle fire up ). We light the fire with a match, the heat from the flame may provide the sufficient energy to to make the reaction happen.
will be produced for the same weight of fuel (RMM is the sum of the
it is lighter than aluminium, and is used in alloys used for aircraft, car engine casings, and missile construction
We humans cannot help but feel a twinge of regret when we contemplate how we brought forth the plague of global warming by our own hands in the passing years. Aside from rising sea levels as deluging coastal cities and depleting ozone layers as increasing cancer rates, we inevitably come face to face with one simple realization: it’s getting too hot in here. Moreover, we have been devastated by various extremes of nature, with spring frost storms and summer hurricanes arriving with increasing frequency. However, numerous though the causes of global warming may be, the general consensus is that carbon dioxide, which results from the burning of fuels such as coal, is the main culprit; this gas has now formed a high concentration blockade in the atmosphere, preventing heat from escaping and thus increasing the temperatures of our planet. Therefore, after assessing all facts of the problem, I humbly propose that we collect the CO2¬, compress it, and then place it into soda cans. Then, we shall store the soda cans underground, whence the CO2 originally came.
Next in the line of fire is fuel. The fuel that scientist think dragons make ...
the air to get the best result. This is to avoid warm air escaping and
Have you ever been sitting there and just wondered about various things dealing with some things in chemistry known as calorimetry or thermochemistry? No, yes, maybe, well whatever your answer you were really thinking yes so I’m going to explain these topics to you in this paper, and teach you how they work so you can figure these things out if you ever run into them I a real life situation.
...burning of fossil fuels has directly enhanced the greenhouse effect and has caused widespread global warming.
25 carbon atoms chemically bonded with 52 hydrogen atoms, 2 oxygen bonded together these two chemically bonded molecules create two things with being bonded they create pariffin wax and oxgen. They are very imporant because wax is the fuel source of the fire and a fire needs oxygen to stay lit. As for the second part which is the products meaning what is made out is carbon dioxide and water vapor. Carbon dixoide is made because it bonds with two oxgen atoms and water vapor is created when two hydrogen and one oxgen molecule bonds. The products that are made are very importanat because it helps keep the fire going and it helps vaporize the wax when it is melting. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light. The reason why there is heat is because of the fire it also produces light because the fire is stable and has a heat source. Experiment seven was about a candle and smoke. The lighter never touched the wick of the candle it always caught fire when put near the
The data collected through the experiment and the graph indicate that there is a positive relationship between the number of carbons in a carbon chain of an alcohol and the enthalpy of combustion of the alcohol. Meaning as the number of carbon atoms in an alcohol chain increases, its enthalpy change of combustion also increases.
must be removed prior to most uses. Natural gas is emerging as the most important
These temperature scales are off by a large margin. There is a specific field of chemistry that studies the heat associated with reactions, and today we begin our journey learning about this form of chemistry called thermochemistry! Thermochemistry is a fascinating field of chemistry that contains new terms and ideas that need to be understood in order to proceed into the mathematical applications of thermochemistry. We are going to create “I wonder.” statements to help with learning about these new terms while we read the text.
