as what once was considered a luxury is now seemingly a necessity. Air-conditioning
manufacturers have played a big part in making units more affordable by increasing their
efficiency and improving components and technology.
An airship is a large lighter-than-air gas balloon that can be navigated by using engine-driven
propellers. There are three types of airships: rigid (has an internal metal frame to maintain the
envelope's shape); semi-rigid (rigid keels run the length of the envelope to maintain its shape);
and non-rigid (internal pressure of the lifting gas, usually helium, maintains the envelope's
Animation is a series of still drawings that, when viewed in rapid succession, gives the

Solar Heating System
In just one second, the Sun gives off 13 million times the energy that is generated by all the
electricity consumed in one year in the United States. Only one millionth of the Sun's energy
reaches Earth, but this scant amount would be more than sufficient to meet the energy
requirements of our entire planet.
Soy sauce is one of the world's oldest condiments and has been used in China for more than
2,500 years. It is made from fermenting a mixture of mashed soybeans, salt, and enzymes.

Institute of Electrical and Electronic Engineers (IEEE). These disturbances—increases in current
that can damage electronic devices plugged into outlets—may be caused by lightning or other
weather-related incidents; traffic accidents affecting power lines; the use of electrical products
such as motors, compressors, and fluorescent lights; high-powered electrical equipment and
voltage fluctuations initiated by a power company; and high-frequency noise.
The hypodermic syringe, also known as the hypodermic needle, is a device used by medical
professionals to transfer liquids into or out of the body. It is made up of a hollow needle, which

abrasives used to clean teeth did not resemble modern toothpastes.
Vitamins are organic compounds that are necessary in small amounts in animal and human diets
to sustain life and health. The absence of certain vitamins can cause disease, poor growth, and a
variety of syndromes.
Wallpaper is a nonwoven (paper) or woven (fabric) backing, decoratively printed for application
to walls of a residence or business. Wallpaper is not considered essential to the decoration of a
structure; however, it has become a primary method by which to impart style, atmosphere, or

The accordion is a portable, freely vibrating reed instrument. It consists of a keyboard and bass
casing that are connected by a collapsible bellows. Within the instrument are metal reeds, which
create sound when air, generated by the movement of the bellows, flows around them and causes
them to vibrate. The accordion is constructed from hundreds of pieces, and much of it is hand
assembled. First constructed in the early nineteenth century, the accordion continues to evolve
into an ever more versatile instrument.
