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 system if the ... is created or brought to its present state from absolute zero, energy must be supplied equal to its internal energy U plus pV, where pV is the work done in ... more interesting to study the internal properties of the system and therefore the internal energy is used ...
Enthalpy - Applications
... 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 ... This internal energy also includes the energy required for activation and the breaking of bonded compounds into gaseous species ... calculations as U + pV, to label the amount of energy or work required to "set aside space for" and "create" the system describing the work done by both the ...
Obesity
... 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, medications ... little yet 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 ... 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 ...
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 dam ... 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 ...

Famous quotes containing the words benefits, alternative and/or energy:

    One of the benefits of a college education is, to show the boy its little avail.
    Ralph Waldo Emerson (1803–1882)

    No alternative to the
    one-man path.
    Denise Levertov (b. 1923)

    While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.
    Emile Durkheim (1858–1917)
