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 a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. At atmospheric pressure, nitrogen is liquid between 63 K and 77 K. Liquids colder than this are considerably more expensive to make than liquid nitrogen is. Nitrogen is used to produce ammonia (Haber process) and fertilizers, vital for current food production methods. It is also used to manufacture nitric acid (Ostwald process). In enhanced oil recovery, high pressure nitrogen is used to force crude oil that would otherwise not be recovered out of oil wells. Nitrogen's inert qualities find use in the chemical and petroleum industries to blanket storage tanks with an inert layer of gas. Liquid nitrogen is used as a refrigerant.
