Centre activities are located at the Centre for Sustainable Energy Systems in the Faculty of Engineering and Information Technology at the Australian National University ... The Director of the ARC Centre for Solar Energy Systems is Professor Andrew Blakers and the Deputy Director is Dr Vernie Everett ...
Enthalpy - Applications
... one can calculate enthalpy by determining the requirements for creating a system from "nothingness" the mechanical work required, pV, differs based upon the constancy of conditions present ... Internal energy, U, must be supplied to remove particles from a surrounding in order to allow space for the creation of a system, providing that environmental variables, such as pressure (p) remain ... This internal energy also includes the energy required for activation and the breaking of bonded compounds into gaseous species ...
Enthalpy Versus Internal Energy
... The U term can be interpreted as the energy required to create the system, and the pV term as the energy that would be required to "make room" for the ... When a system, for example, n moles of a gas of volume V at pressure p and temperature T, is created or brought to its present state from absolute zero ... to study the internal properties of the system and therefore the internal energy is used ...
Transformations of Energy
... One form of energy can often be readily transformed into another with the help of a device- for instance, a battery, from chemical energy to electric energy a ... Similarly, in the case of a chemical explosion, chemical potential energy is transformed to kinetic energy and thermal energy in a very short time ... At its highest points the kinetic energy is zero and the gravitational potential energy is at maximum ...
... is most commonly caused by a combination of excessive food energy intake, lack of physical activity, and genetic susceptibility, although a few cases are caused primarily by genes, endocrine disorders ... gain weight due to a slow metabolism is limited on average obese people have a greater energy expenditure than their thin counterparts due to the energy required to maintain an increased body mass ... Diet quality can be improved by reducing the consumption of energy-dense foods such as those high in fat and sugars, and by increasing the intake of dietary fiber ...

Famous quotes containing the words systems, solar and/or energy:

    In all systems of theology the devil figures as a male person.... Yes, it is women who keep the church going.
    Don Marquis (1878–1937)

    Senta: These boats, sir, what are they for?
    Hamar: They are solar boats for Pharaoh to use after his death. They’re the means by which Pharaoh will journey across the skies with the sun, with the god Horus. Each day they will sail from east to west, and each night Pharaoh will return to the east by the river which runs underneath the earth.
    William Faulkner (1897–1962)

    There are no accidents, only nature throwing her weight around. Even the bomb merely releases energy that nature has put there. Nuclear war would be just a spark in the grandeur of space. Nor can radiation “alter” nature: she will absorb it all. After the bomb, nature will pick up the cards we have spilled, shuffle them, and begin her game again.
    Camille Paglia (b. 1947)
