Volume fraction

In chemistry, the volume fraction φi is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing:

Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%.

The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).

The sum of all volume fractions of a mixture is equal to 1:

The volume fraction (percentage by volume, vol%) is one way of expressing the composition of a mixture with a dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others.

Volume percent

Volume percent is a common expression of a solution's concentration. It is the volume fraction expressed with a denominator of 100, and thus is defined as:

Vol (heraldry)

A vol (French for "flight") is a once-obscure heraldic symbol consisting of a pair of outstretched, usually plumed bird's wings, which are connected together at their shoulders without having any bird's body in the middle.

The French Armée de l'Air, one of the world's first air forces, adopted a vol for its cap badge, rather than the eagle used by many other air forces. In France, the eagle is associated with the Napoleonic empire.

Cap badges

Many European countries have an eagle as the main charge of the heraldic shields of their respective monarchies: Germany, Austria-Hungary, and pre-revolutionary Russia all used some derivative of this bird in their badge. Poland did too, and even kept its badge under Communist rule, because Poland did not have a king since the partition of Poland late in the eighteenth century, so the symbol was merely nominal. In America, the cap badge of the US Air Force is the Great Seal of the United States, which also includes an eagle. But its use for the US Air Force derives from that service's derivation from the US Army, which also had the same badge.

Vol. 4 (Black Sabbath album)

Vol. 4 is the fourth studio album by English heavy metal band Black Sabbath, released in September 1972. It was the first album by Black Sabbath not produced by Rodger Bain; guitarist Tony Iommi assumed production duties. Patrick Meehan, the band's then-manager, was listed as co-producer, though his actual involvement in the album's production was minimal at best.

Recording

In June 1972, Black Sabbath reconvened in Los Angeles to begin work on their fourth album at the Record Plant Studios. The recording process was plagued with problems, many due to substance abuse issues. In the studio, the band regularly had large speaker boxes full of cocaine delivered. While struggling to record the song "Cornucopia" after "sitting in the middle of the room, just doing drugs",Bill Ward feared that he was about to be fired from the band. "I hated the song, there were some patterns that were just horrible", Ward said. "I nailed it in the end, but the reaction I got was the cold shoulder from everybody. It was like 'Well, just go home, you're not being of any use right now.' I felt like I'd blown it, I was about to get fired". According to the book How Black Was Our Sabbath, Bill Ward "was always a drinker, but rarely appeared drunk. Retrospectively, that might have been a danger sign. Now, his self-control was clearly slipping." Iommi claims in his autobiography that Ward almost died after a prank-gone-wrong during recording of the album. The Bel Air mansion the band was renting belonged to John DuPont of the DuPont chemical company and the band found several spray cans of gold DuPont paint in a room of the house; finding Ward naked and unconscious after drinking heavily, they proceeded to cover the drummer in gold paint from head to toe.

    Lullacry

    Lullacry was a melodic band with gothic metal influences that hailed from Helsinki, Finland. The band recorded their first demo (named Weeper's Aeon) in 1998 and in a short time they had enough of a following to safely attempt a full-length album – Sweet Desire – recorded in 1999. This got the attention of Spinefarm Records and led to a professional contract. Their career truly began progressing after the release of the album Be My God – from 2001 – which was issued as they went on a joint tour with the power metal band Edguy.

    However, vocalist Tanya Kemppainen quit the band in 2002, leaving Lullacry without its main element. Many female singers applied for the post, but the then unknown contralto vocalist Tanja Lainio was ultimately chosen as the replacement vocalist. Their following release was entitled Crucify My Heart. The single Don't Touch the Flame taken from this album included a cover of the Nine Inch Nails track Head Like a Hole.

    Prior to the recording of their fourth album, the EP Fire Within was released including alternative versions of two of the band's classic tracks, a W.A.S.P. cover "L.O.V.E. Machine", and two new tracks.

    Think of a rectangular prism as a 3 dimensional rectangle. To find the volume of a rectangular prism let's start by finding the volume of a rectangle, and go from there. What do you think we do next??

You'll be able to add, subtract, multiply, and divide any non-negative numbers (including decimals and fractions) that any grumpy ogre throws at you. Mind-blowing ideas like exponents (you saw these briefly in the 5th grade), ratios, percents, negative numbers, and variable expressions will start being in your comfort zone. Most importantly, the algebraic side of mathematics is a whole new kind of fun! And if that is not enough, we are going to continue with our understanding of ideas like the coordinate plane (from 5th grade) and area while beginning to derive meaning from data! (Content was selected for this grade level based on a typical curriculum in the United States.)

    Volume fraction

    In chemistry, the volume fraction φi is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing:

    Being dimensionless, its unit is 1; it is expressed as a number, e.g., 0.18. It is the same concept as volume percent (vol%) except that the latter is expressed with a denominator of 100, e.g., 18%.

    The volume fraction coincides with the volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).

    The sum of all volume fractions of a mixture is equal to 1:

    The volume fraction (percentage by volume, vol%) is one way of expressing the composition of a mixture with a dimensionless quantity; mass fraction (percentage by weight, wt%) and mole fraction (percentage by moles, mol%) are others.

    Volume percent

    Volume percent is a common expression of a solution's concentration. It is the volume fraction expressed with a denominator of 100, and thus is defined as:
