Coefficient of Thermal Expansion of Gasoline?
Do you believe the Coefficient of Thermal Expansion of Gasoline is high enough to make it worth it to only buy gas at night when it is cold?

Gasoline - 0.000950 / (C or K)
We'll say a 15 degree (C or K) temperature change.
ΔV = V0βΔT
ΔV = (1gallon)(0.000950)(15)
ΔV = 0.01425gallons
So at night, you get 1 gallon and the next day it expands to 1.01425 gallons.
It breaks down to this:
During the day you pay $40. At night you would get that same amount of gas for $39.44.Source(s): . . You save ~1% for every 10C drop in temperature. . .

Although it 1 gallon of hot gasoline contains less substance,
it does not mean that that when you buy 1 gallon of hot
gasoline you buy less. The trick is that while you assume
that the pump pours the exact volume as it displays,
in relaity it displays what it _thinks the volume is.
The parts of measuring mechanism undergo thermal
expansion too, and it affects measurement errors.
For example if you imagne that there is a homonuclus
inside the pump, who pours you 1000 teaspoonful of gasoline
whenever you by one gallon, the actual result depend
on the volume of the teaspoon, which expands with

Using a graph, the coldest part of the day is not at night but just before the sun rises
