**Week
Two: Outside Lab Measurement Project:**

**My Primary Gasoline Demand**

In Chemistry
we collect data in the laboratory while performing an experiment. Our second
lab concerns

measurement and data collection. As an additional
experiment which can be performed by you collecting data over

the next 3 to 4 months, we can find out
what our energy cost are for driving a car. So here is the project which we

will start ASAP and finish the last week
of the term:

**Energy Project: My Gasoline Demand**

** **

** **

During
the first weeks of class you need to fill your gasoline tank in your car.
During the course you will keep a record of all

purchases of gasoline noting dates, price, amount, cost and
odometer reading. Get receipts or keep a diary in your vehicle. Then

transfer each purchase to a data page or in a spreadsheet.
Collecting the data and presenting the data collected is one half the grade

or 20 points. This lab counts as four labs as it is an
intense 12-16 week project or 40 points.

During the last weeks, you fill your tank again
and record the data. You will determine:

- The
**Total Miles driven; the Total Gallons Used; the Total Cost; and the Total Days of the Project**.

**Total
Miles Driven**: Subtract you initial
odometer reading from the your final Odometer Reading

**Total
gallon Used**: Sum all your Gallons
Purchased, except do not include the gallons recorded in your initial fill-up
(Why?)

**Total
Cost:** Sum all your dollars spent
during the project, except the initial fill-up. (Why?)

- Then
you will compute the average MPG and the average cost per mile for the
gasoline.

**MPG** = Total Miles Driven divided by Total Gallons
Used

**Average
Cost Per Mile** = Total Dollars Spent divided by Total Mile Driven

- You
will also calculate your average daily mileage and average daily gallons
of gasoline used:

**Average
daily Miles** = Total Miles Driven
divided by Total Days of the Project

**Average
Daily Gallons Used** = Total Gallon Used
divided by Total Days of the Project

- How many times did you exceed 75 miles in
one day?

(You may not be able to answer this, but
statistics say that the average U.S. driver averages 29 miles per day and this
can be

skewed if you took a long trip during the project to
see if you are average)

- What
is your annual mileage:

**Annual
Mileage** = your daily average miles
driven calculated above multiplied by 365 days

- your projected annual need for gasoline:

**Annual
Gasoline Demand**: Your average Gallons Used
multiplied by 365 days

- What
will be annual cost at $2.00 per gallon; $3.00 per gallon; $3.50 per
gallon; $4.00 per gallon; $4.50 per gallon; and $5.00 per gallon.

**Annual
Cost @ $2.00/gallon** = Yearly Gasoline Demand(gallons) multiplied by $2.00/gallon

**Annual
Cost @ $3.00/gallo**n = Yearly Gasoline Demand(gallons) multiplied by $3.00/gallon

**Annual
Cost @ $3.50/gallon** = Yearly Gasoline Demand(gallons) multiplied by $3.50/gallon

**Annual
Cost @ $4.00/gallon** = Yearly Gasoline Demand(gallons) multiplied by $4.00/gallon

**Annual
Cost @ $4.50/gallon** = Yearly Gasoline Demand(gallons) multiplied by $4.50/gallon

**Annual
Cost @ $5.00/gallon** = Yearly Gasoline Demand(gallons) multiplied by $5.00/gallon

**Total Pounds of Carbon Dioxide released into the atmosphere by you every year.**

**Total
Annual CO _{2} Released = Total Annual Gallons Used multiplied by 19
pounds/gallon**

i. The instructor may add additional data for you
to determine to complete this project**.
Presentation and projections are worth**

** one half the grade or
20 points. If your family has more than one car, extra credit may be earned for
doing two projects**

** for the 12-16 weeks.**

**These
calculations should be done in a spreadsheet or typed in table format, but the
spreadsheet may either be hand drawn on your data page or done on the computer.
You may also keep your data in your lab notebook.**

**You
need to only fill the tank twice, at the beginning and at the end of the
project. You will not use the first fill-up in your calculations, except
odometer reading. Why?**

**If you
do not drive or own a vehicle and can not get cooperation from your family, the
instructor will assigned an alternate energy demand project or you may earn
20-40 total points using the data of your instructor’s car.**

Discussion:

My concept of
driving with the increase cost of gasoline, is to have a car which gets at
least 20 miles per gallon; but

spend approximately
only 5 to 10 cents a mile cost of the vehicle. At $4 per gallon that is 20
cents per mile to drive

plus 10 cents
purchase cost per mile…totally 30 cents or less per mile.

In 1985 I
purchased my last brand new car. It was a GM Tech 4 engine which got 27-37 mpg.
Before that it was1963

when I got my first
20 mpg car a VW Karman Ghia. My very first car was a
55 ford coupe in 1958 which got only 8

mpg. (Gasoline then was 14 cents a
gallon. I got upset in 1962 when gas jumped to 17-18 cents a gallon and so I

went for the 20 mpg. Have a laugh, but
think about it a 4 cent jump was almost a 30% increase. Today that equates

to $3 to $3.90. Remember minimum wage in
1962 was 40 cents an hour, which was $16 per week for a worker trying

to just get by.

All the cars in between have been used from
excellent to tired old beat-up cars, sometime I call them Throw away

cars (Spend $1000
drive it 10,000 miles then throw it away: cost 10 cents per mile).

I am very
concerned about our environment. No matter how many mpg you get,
every gallon of gasoline you burn

produces almost 19 pounds of Carbon Dioxide
into our atmosphere. If we drive electric, then the equivalent for a

gallon of gasoline in electricity purchased
from a fossil fuel company (Like JEA) created between 4 to 5 pounds of

CO_{2} into the
atmosphere which saves the environment 13-14 pounds of CO_{2} per
equivalent gallon used.

The chemical
reaction for combusting gasoline is:

2 C_{8}H_{18} (l) + 25 O_{2}
(g) à 16
CO_{2} (g) + 18 H_{2}O (g)

By Module 5
we will prove the stoichiometry of this reaction and
prove the 18.7 pounds per gallon burned.

Since 2009 I
have been preaching we need to drive all electric. You need to research the
only real plan to save

America is the T-Boon Pickens Plan but that
requires the use of more Natural Gas..

However, due
to our Florida Government in 2010, the electric initiative has been put on the
back burner. In January

2011 I drove the Niasen
LEAF. Loved the car. Immediately my wife wanted to
write a check for $25K and buy it for

me. WOW!

A month later I drove the Chevy VOLT…more
realistic than the LEAF for Florida, but it wasn’t Toyota and my wife

hates American. (I
have always driven American cars, except my VW, my wife has driven Toyota for
the last 30

years). OK, I decided
to go hybrid, make my wife happy, but not save the environment as much.

Toyota granted me the option to purchase the
very first plug in Prius in the third quarter of 2012, but my
frustration

with local
dealerships I had to compromise. My wife
bought the 2012 Version III Prius. OK 48-51 mpg
versus 69-75

mpg. The plug-in Prius is best option on the road and it is now appearing on
the roads since fourth quarter 2012.

You can run 14 miles at under 62 mile per hour
on pure electric and plug into 120 volt standard outlet, while

generation III Prius 3-4 miles at speeds under 38 mpg does not have the
plug in option. Average 75 miles per gallon

versus 46 miles per
gallon is the comparison. So how much will it cost to buy the electricity?

On Sunday,
January 11, 2015 there was an interesting up date to electric cars, GM will be selling the BOLT in 2016,

an all electric which
gets 200 miles on a full charge. The Volt will be modified to get up to more
electric car miles

than 38. Tesla is
coming out with a $35K car that goes 200 miles on a charge and the LEAF will be
also modified.
