See your doctor right away if you have signs of a urinary tract infection. A bladder infection is generally not a medical emergency -- but some people have a higher risk for complications. This includes pregnant women, the elderly, and men, as well as people with diabetes, kidney problems, or a weakened immune system.ormones cause changes in the urinary tract, and the uterus may put pressure on the ureters or bladder or both -- making it more difficult for urine to pass from the kidneys to the bladder and out. Untreated UTIs can contribute to preterm labor, so be sure to alert your doctor if you suspect you have an infection.
Hydrogen gas has the molecular formula H 2. At room temperature and under standard pressure conditions, hydrogen is a gas that is tasteless, odorless and colorless. Hydrogen can exist as a liquid under high pressure and an extremely low temperature of 20.28 kelvin (â252.87Â°C, â423.17 Â°F). Hydrogen is often stored in this way as liquid hydrogen takes up less space than hydrogen in its normal gas form. Liquid hydrogen is also used as a rocket fuel.
Word History of HYDROGEN. When hydrogen is burned it combines with oxygen to make water. That fact accounts for the name of this gas. The word hydrogen was formed from two Greek roots. The first, hydro- , means â water, â and the second, -gen, means â giving rise to, producing.â.ull Definition of HYDROGEN. : a nonmetallic element that is the simplest and lightest of the elements, is normally a colorless odorless highly flammable diatomic gas, and is used especially in synthesis â see element table â compare deuterium, tritium.
