A male standing erect can be 5â6 feet (1.5â1.8 m) tall and weigh 300â600 pounds (140â270 kg). According to the Guinness Book of World Records, the average male is 168 kg (370 lb) and stands upright at 163 cm (64 in). Males in captivity, however, are noted to be capable of reaching weights up to 275 kg. Females stand 5 feet (1.5 m) tall and weigh half as much as males. According to the late John Aspinall, a silverback gorilla in his prime has the physical strength of 7â8 Olympic weight lifters but this claim is unverified.
NP-3 | Nitrogen Plastic Welder. The Nitrogen Plastic Welder uses hot nitrogen gas to restructure common plastic components in automotive repair â from cracked bumper cover surfaces to hinged tabs. Nitrogen is used as a shielding gas to prevent the plastic from burning during the weld process â producing a strong, lasting weld.
Nitrogen is obtained from liquefied air through a process known as fractional distillation. The largest use of nitrogen is for the production of ammonia (NH 3). Large amounts of nitrogen are combined with hydrogen to produce ammonia in a method known as the Haber process. Large amounts of ammonia are then used to create fertilizers, explosives and, through a process known as the Ostwald process, nitric acid (HNO 3). Nitrogen gas is largely inert and is used as a protective shield in the semiconductor industry and during certain types of welding and soldering operations.
