Pressure Canning: A Step-By-Step Guide. Pressure Canning The lid of a pressure canner with weighted gauge. Leda Meredith If you want to can unpickled vegetables, soup stocks, beans, or any non-acidic food, youâve got to use a special piece of equipment called a pressure canner.
Saturn is the second largest planet in our solar system and the sixth in distance from the Sun. It is mostly gaseous with large rings of ice and rocks. It has more than 60 mâ¦oons, the inner ones small and within the ring system. The outer hydrogen atmosphere is very cold, as low as -200 Â°C.
In the top one-fourth of the planet, the pressure and temperature are so high that the hydrogen atoms are stripped of their outer electrons, forming a liquid metal. Like Jupiter, Saturn has a thick atmosphere composed of hydrogen and helium. The ratio of hydrogen to helium ratio decreases with depth. Methane and ammonia are also present. The atmosphere of Saturn envelops a thick layer of metallic hydrogen. The atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere are composed of crystals of methane. -=-=-=-=- Since gas giants do not actually have a surface, it is rather difficult to determine where their atmospheres end.
