What is Matter? - Correct Answers-Matter is anything that has mass and occupies space. It
contains millions of invisible particles called molecules
What is Matter made of? - Correct Answers-Matter is made of molecules and atoms
What is a Molecule? - Correct Answers-A molecule is the smallest particle into which matter
can be divided without changing its identity and still be called by the same name. All molecules
are composed of atoms.
What is an Electrical Current? - Correct Answers-It is Electricity in motion and represents the
transfer of energy from one place to another and the flow of electrons in a conductor.
Electricity is also capable of converting energy from one form to another.
Name six sources of power from raw energy - Correct Answers-Coal, oil, natural gas, uranium,
wood & wind.
Name the three specialized technical steps that provide electricity - Correct Answers-
Generation, Transmission & Distribution
How does a generator plant produced electricity - Correct Answers-Its produce by turning a
shaft, on which is mounted a powerful electromagnet. The shaft turns inside a cylindrical iron
shell called a stator. The rotating electromagnetic field, acting on wire coils in the stator,
produces electricity.
What is a Volt? - Correct Answers-It is the unit of electrical pressure or electromotive force or
potential difference. Electricity flowing along a wire may be compared to water flowing through
a pipe.
What is the atom? - Correct Answers-It is the smallest particle that makes up that type of
material called an ELEMENT.
What retains its characteristics when subdivided into atoms? - Correct Answers-Elements
What is the core of the atom called - Correct Answers-Nucleus
Where is most of the mass of the atom concentrated in? - Correct Answers-Nucleus
