    Does temperature have an effect on the WEIGHT of fuel? It has an effect on the volume but not weight correct? Example... A gallon of cold fuel will weigh the same as a gallon of hot fuel, but the hot fuel will just take up more volume..... is this a correct statement???

    When heating a gallon of fuel, its volume will become greater than one gallon, but it will still weigh the same as when it was cold (assuming no evaporation).


    ...Wait, what?

    Ok.... So in the same effect.... you fill a gallon container with cold fuel, and you fill a separate gallon container with hot fuel.... the gallon container of hot fuel will weigh less than the gallon container of cold fuel because it is less dense... same volume(1 gallon), different weight... correct?
    lol! Sorry, for the strange questions!

    For almost all substances, an increase in temperature means a decrease in volume. This also means a decrease in density (m/V). (Water is an exception since ice is less dense than liquid water)

    A gallon of a hot substance would have a mass that is very slightly lower than a gallon of the same substance, but cold.
