Graphite is a naturally-occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous rocks. Graphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure and has a very low specific gravity.ome graphite forms from the metamorphism of coal seams. The organic material in coal is composed mainly of carbon, oxygen, hydrogen, nitrogen and sulfur. The heat of metamorphism destroys the organic molecules of coal, volatilizing the oxygen, hydrogen, nitrogen and sulfur.
The normal respiration rate for an adult is 14â20 breaths per minute. Newborns have a rate of 30â60 breaths per minute. Infants have 24â 40 breaths per minute, and children ages 1â7 have a rate of 22â34 breaths per minute. patient breath The normal pulse rate for an adult is between 60â100 beats per minute. Children and infants tend to have a faster pulse rate, between 120â170 beats per minute.
ventilation status is done by. This is done by accessing the rate at which gas moves into and out of the lungs. The respiration rate is measured by. The respiration rate is measured by counting the number of breaths taken in a minute. In a resting adult, the respiration rate ranges In a resting adult, the respiration rate ranges from 12 to 18 breaths per minutes, in children it ranges whereas in children it ranges from 18-20 breaths/minute.
