Energy Applications

Across

2. The function of the state of a thermodynamic system whose change in any differential reversible process is equal to the heat absorbed by the system from its surroundings divided by the absolute temperature of the system.
4. The unit of potential difference symbolized as V.
7. Law of Thermodynamics A law that if two systems are separately found to be in thermal equilibrium with a third system, the first two systems are in thermal equilibrium with each other; that is, all three systems are at the same temperature. Also known as thermodynamic equilibrium.
12. A property of an object which determines the direction of heat flow when the object is placed in thermal contact with another object.
15. A measure of thermal transmittance through a material.
16. Development Lifecycle Stages a product goes through from concept and use to eventual withdrawal from the market place.
17. Energy Any source of energy other than fossil fuels that's used for constructive purposes
19. Solar Energy Collection Systems that do not make use of any externally powered, moving parts, such as circulation pumps, to move heated water or air.
21. Energy Energy caused by the movement of light waves.
23. System A part of the physical world as described by its thermodynamic properties such as temperature, volume, pressure, concentration, surface tension, and viscosity.
26. Law of Thermodynamics A general statement of the idea that there is a preferred direction for any process.
27. process by which a fluid is being heated, the warmer part of the mass will rise and the cooler portions will sink
29. Energy A resource that can be replaced when needed.
31. Energy in transit due to a temperature difference between the source from which the energy is coming and a sink toward which the energy is going.
32. Cell Stack Individual fuel cells that are combined in series.
33. of Best Fit A straight line that best represents all data points of a scatter plot. This line may pass through some, all, or none of the points displayed by the scatter plot. Also referred to as a Trend Line or Regression Line.

Down

1. Law of Thermodynamics The law that heat is a form of energy, and the total amount of energy of all kinds in an isolated system is constant; it is an application of the principle of conservation of energy. Also known as conservation of energy.
3. The opposition that a device or material offers to the flow of direct current.
5. The study of the effects of work, heat, and energy on a system.
6. Law States that the direct current flowing in an electric circuit is directly proportional to the voltage applied to the circuit.
8. The flow of electrical power or charge.
9. The net transfer of electric charge (electron movement along a path) per unit of time.
10. A unit of absolute temperature and symbolized as K. Formerly known as degree Kelvin.
11. Equilibrium Refers to the property of a thermodynamic system in which all parts of the system have attained a uniform temperature which is the same as that of the system’s surroundings.
13. The potential difference measured in volts. The amount of work to be done to move a charge from one point to another along an electric circuit.
14. The unit of electrical current; referred to as amp
18. The process separating the hydrogen-oxygen bond in water using an electrical current.
20. energy Energy caused by the movement of electrons.
22. The transfer of heat within or between objects by molecular activity, without any net external motion
24. The unit of electric current in the meter-kilogram-second system of units. Symbolized as Ω.
25. The process by which energy is transmitted through a medium, including empty space, as electromagnetic waves. This energy travels at the speed of light. This is also referred to as electromagnetic radiation.
28. The ability to do work.
29. The measure of resistance to heat flow.
30. Solar Energy Collection System that uses circulating fans and pumps to collect and distribute heat
