Energy of movement

Equation (22) was obtained, essentially, with examination of the energy balance equation with respect to flows of gas-containing polymer melts. The key moment of this analysis is, in our view, comprehension of the fact that the energy of gas dissolved in the polymer is transformed into the energy of movement of the two-phase medium. [Pg.117]

The constituent particles of a substance each have energy. In practice, the energy is manifested as kinetic energy - the energy of movement - and explains why all molecules and atoms move continually as an expression of that kinetic energy. This energy decreases as the temperature decreases. The particles only stop moving when cooled to a temperature of absolute zero 0 K or —273.15 °C. [Pg.30]

For simplicity, we will consider only the molecules of gas. Each molecule of gas will have kinetic energy (the energy of movement) unless the temperature is absolute zero. This energy may be transferred through inelastic molecules collisions. But how much kinetic energy does the gas have ... [Pg.33]

Generator— A device for converting kinetic energy (the energy of movement) into electrical energy. Isotopes—Two molecules in which the number of atoms and the types of atoms are identical, but their arrangement in space is different, resulting in different chemical and physical properties. [Pg.600]

There are two principal forms of energy kinetic and potential. Kinetic energy is the energy of movement—the motion of molecules, for example. The second form of energy, potential energy, or stored energy, is particularly Important in the study of biological or chemical systems. [Pg.50]

Kinetic energy is the energy of movement and potential energy is stored energy... [Pg.48]

The act of crystallization is a sudden process, which occurs at the precise temperature at which the energy of movement yields to the forces of attraction. In an amorphous solid, the molecules gradually become slower and more closely attracted to one another, until they are so closely packed that they completely impede one another and the substance will not flow. It is impossible to say exactly when this occurs, or even whether the substance has changed from flowing very slowly indeed, to not flowing at all. There is no melting point and the boundary between the solid and the liquid state is blurred. [Pg.59]

The particles are always moving in some way - they have energy of movement. Heating gives the particles more energy of movement - they are more energetic. [Pg.54]

A steam turbine is a device driver that converts kinetic energy (steam energy of movement) to mechanical energy. Steam turbines have a specially designed rotor that rotates as steam strikes it. This rotation is used to operate a variety of shaft-driven equipment. The steam used to operate a steam turbine is produced in a boiler. Boilers produce steam that can enter a turbine at temperatures as high as 1,000°F, and pressures as high as 3,500 psi inlet and 200 psi outlet. High-pressure steam is slowly admitted into a turbine to warm it up and remove the condensate. [Pg.132]

In statistical mechanics (e.g. the theory of specific heats of gases) a degree of freedom means an independent mode of absorbing energy by movement of atoms. Thus a mon-... [Pg.127]

In order to reach a crystalline state, polymers must have sufficient freedom of motion. Polymer crystals nearly always consist of many strands with a parallel packing. Simply putting strands in parallel does not ensure that they will have the freedom of movement necessary to then find the low-energy con-former. The researcher can check this by examining the cross-sectional profile of the polymer (viewed end on). If the profile is roughly circular, it is likely that the chain will be able to change conformation as necessary. [Pg.311]

Descriptions of Physical Objects, Processes, or Abstract Concepts. Eor example, pumps can be described as devices that move fluids. They have input and output ports, need a source of energy, and may have mechanical components such as impellers or pistons. Similarly, the process of flow can be described as a coherent movement of a Hquid, gas, or coUections of soHd particles. Flow is characterized by direction and rate of movement (flow rate). An example of an abstract concept is chemical reaction, which can be described in terms of reactants and conditions. Descriptions such as these can be viewed as stmctured coUections of atomic facts about some common entity. In cases where the descriptions are known to be partial or incomplete, the representation scheme has to be able to express the associated uncertainty. [Pg.531]

In rooms where air and contaminant movement is dominated by thernnal energy of heat sources (e.g., in rooms with natural or displacement ventilation), temperature and contaminant stratification along the room height is created. Air supply and exhaust in such rooms are designed not to disturb the natural pattern of air movement created by heat sources cooled air enters the room in... [Pg.436]
