A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. The capacity of the air conditioning depends entirely on the capacity of the compressor. The reciprocating compressor is usually used in AC.

The reciprocating compressor have piston and cylinder arrangement like the automotive engine. The reciprocating motion of the piston due to external power compresses the refrigerant inside the cylinder.

There are three types of reciprocating compressors:

hermetically sealed,

semi-hermetically sealed and

open type.

Allows for expansion or contraction of the trachea. Hence, so large masses of food can pass through the esophagus during swallowing.

Oxygen is transported throughout the body via hemoglobin in the red blood cells. Hence, most of the oxygen transported by the blood is bounded to hemoglobin.

Salts and sugars work to preserve foods by creating a Hypertonic environment.

The device which is used to measure air pressure is called as barometer. If the barometer reading is rising, it indicates that the air pressure is increasing and if the reading is falling the air pressure is decreaing.

Agriculture would be a good example of a purely competitive industry.
