Energy & Power Terms 2016-01-31

Energy & Power Terms crossword puzzle
Across
  1. the energy associated with the random, disordered motion of molecules. It is separated in scale from the macroscopic ordered energy associated with moving objects; it refers to the invisible microscopic energy on the atomic and molecular scale.
  2. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed.
  3. energy is a property of objects which can be transferred to other objects or converted into different forms, but cannot be created or destroyed.
  4. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
  5. energy that is collected from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.
  6. a force is said to do work if, when acting on a body, there is a displacement of the point of application in the direction of the force
  7. natural resource that will never run out so if we take advantage of the greatest natural resources will not be depleted and will continue to exist, such as water, sunlight, tidal energy, ocean energy and wind energy.
  8. the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Down
  1. the unit of power
  2. the rate of doing work. It is equivalent to an amount of energy consumed per unit time. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.
  3. energy sources that have no undesired consequences such for example fossil fuels or nuclear energy. Alternative energy sources are renewable and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources.
  4. fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.
  5. a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 meters per second on earth. The formula for potential energy due to gravity is PE = mgh.
  6. a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
  7. the entropy of an isolated system always increases, and is often called the law of increased entropy. Entropy (S) is disorder or chaos in a system. In other words, entropy measures the energy in a system unavailable for work.
  8. organic matter derived from living, or recently living organisms. Biomass can be used as a source of energy and it most often refers to plants or plant-based materials which are not used for food or feed, and are specifically called lignocellulosic biomass .
  9. a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.

17 Clues: the unit of power • a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms. • a force is said to do work if, when acting on a body, there is a displacement of the point of application in the direction of the force • ...
