Difference of gasoline when you fill in at different temperatures

We know objects are expanding when the temperature goes up. Therefore, I always think that I should fill in my gasoline in my car in the early morning so that I could have more gasoline when I spend the same money. But how much really we could gain if the temperature changes fill in gasoline at 60°F instead of 80°F (this is actually the changes of temperature at Berkeley during the morning and noon). I want to have a rough estimation of what's the difference between the amount of gasoline when I fill in at different times of the day. To calculate the change of the gasoline, we need to use the physics that we learned in high school, the basic equation is the following one, that relates the volume change of an object to the temperature change.
\Delta = \beta\times T \times \DeltaT
\DeltaV is the change of the volume, and \beta is the average coefficient of volume expansion, and the V is the initial volume of the object, and \DeltaT is the change of the temperature. Therefore, all we need to do is to find the coefficient of volume expansion, and it is 9.6\times 10^{-4}/C°, that is 5.33\times 10^{-4}/F°. Now, let’s assume that we fill in 10-gallon gasoline in the morning at 60°F and how much it will be at noon (80°F)
delta_v = 5.33e-4 * 10 * (80-60)
print('We gain %.2f gallon gasoline, \nif we fill in the morning instead of noon.'%delta_v)
We gain 0.11 gallon gasoline, 
if we fill in the morning instead of noon.
Well, it is 0.11-gallon difference if we fill in 10-gallon gasoline in the morning (that is, we will have 10.11 gallon at noon when temperature increases to 80°F). Let’s calculate how much we potentially can save if we drive our car for certain distances.
Let’s say your car’s average MPG is 30, for 150,000 miles, we need 150,000 / 30 = 5000-gallon gasoline. The difference of gasoline will be 5000 / 10 \times0.11 = 55gallon.

  1. Great post full of useful tips! My site is fairly new and I am also having a hard time getting my readers to leave comments. Analytics shows they are coming to the site but I have a feeling "nobody wants to be first"Jogo para criança online

    1. My husband and I have been married for about 7 yrs now. We were happily married with two kids, a boy and a girl. 3 months ago, I started to notice some strange behavior from him and a few weeks later I found out that my husband is seeing someone. He started coming home late from work, he hardly care about me or the kids anymore, Sometimes he goes out and doesn't even come back home for about 2-3 days. I did all I could to rectify this problem but all to no avail. I became very worried and needed help. As I was browsing through the Internet one day, I came across a website that suggested that Dr Great can help solve marital problems, restore broken relationships and so on. So, I felt I should give him a try. I contacted him and he did a spell for me. Two days later, my husband came to me and apologized for the wrongs he did and promise never to do it again. Ever since then, everything has returned back to normal. I and my family are living together happily again.. All thanks to Dr Great . If you need a spell caster that can cast a spell that truly works, I suggest you contact him. He will not disappoint you. This is his E-mail:

Not a soul would have been able to influence me about magical spells, not until DR GREAT did it for me and restored my marriage of 8 years and brought my spouse back to me in the same 24 hours just as i read on the internet..i was truly astonished and shocked when my husband knelt down begging for forgiveness and for me to accept him back.. I am really short of expressions, and i don't know how much to convey my appreciation to you DR GREAT you are a God sent to me and my entire family.. And now i am a joyful woman once again..

  5. My name is Tom cam!!! i am very grateful sharing this great testimonies with you all, The best thing that has ever happened in my life, is how i worn the Powerball lottery. I do believe that someday i will win the Powerball lottery. finally my dreams came through when i contacted Dr. OSE and tell him i needed the lottery winning special numbers cause i have come a long way spending money on ticket just to make sure i win. But i never knew that winning was so easy with the help of Dr. OSE, until the day i meant the spell caster testimony online, which a lot of people has talked about that he is very powerful and has great powers in casting lottery spell, so i decided to give it a try. I emailed Dr. OSE and he did a spell and gave me the winning lottery special numbers 62, and co-incidentally I have be playing this same number for the past 23years without any winning, But believe me when I play the special number 62 this time and the draws were out i was the mega winner because the special 62 matched all five white-ball numbers as well as the Powerball, in the April 4 drawing to win the $70 million jackpot prize...… Dr. OSE, truly you are the best, with Dr. OSE you can will millions of money through lottery. i am a living testimony and so very happy i meant him, and i will forever be grateful to him...… you can Email him for your own winning special lottery numbers now oseremenspelltemple@gmail.com OR WHATSAPP him +2348136482342

  7. Thank you Dr Jumba for your genuine spells. This is really incredible, and I have never experienced anything like this in my life. Before I came in contact with Dr Jumba, I have tried every possible means that I could to get my husband back, but I actually came to realize that nothing was working out for me, and my husband had developed a lot of hatred for me.. I thought there was no hope of reuniting with my husband until my friend told me about dr jumba and she gave me dr jumba website i googled it and read good reviews about Dr Jumba work , I decided to give it a try and I did everything that he instructed me and I trusted in him and followed his instructions just as he had guaranteed me in 24 hours, and that was exactly when my husband called me and ask for forgiveness that he his on his way to my house .. We are good more than ever. Everything looks perfect and so natural! Thank you so much for your authentic and indisputable spells. Thank you Dr Jumba for your help.
