General Science is a yearlong laboratory course designed to give students continued experience in Physical, Earth, and Life Science. Physical science concepts covered include basic chemistry, energy, motion, acceleration, electricity, and matter. Earth science topics include space, the solar system, and basic ecology. The body systems are covered in the life science chapters. IGS offers insight into the means by which scientific knowledge is acquired and applied. This is done primarily through experimentation and problem solving. This course is designed to serve as a solid foundation for students taking later courses in Chemistry and Physics.

General Science: General Physics Practice MCQ

Question Statement:

Crystals of which of the following naturally-occuring substance exhibits both ‘pyroelectric’ and ‘piezoelectric’ properties making it versatile for application in the field of electronics?

Quartz

Mica

Topaz

grapite

Explanation:

Correct Answer: A

Quartz crystals have piezoelectric properties: they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. A common piezoelectric use of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. Quartz is also strongly pyroelectric. Temperature changes create positive and negative charges within the crystal.
