Deutsch: Halogene / Español: Halógeno / Português: Halogénio / Français: Halogène / Italiano: Alogeni
A halogen is a member of the chemical group of halogens. It is the only periodic table group that contains elements in all three familiar states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen. Most halogens are typically produced from minerals of salts. The middle halogens, that is, chlorine, bromine and iodine, are often used as disinfectants. The halogens are also all toxic.

Hemp is a commonly used term for varieties of the Cannabis plant and its products, which include fiber, oil, and seed. In many countries regulatory limits for concentrations of psychoactive drug compounds (THC) in hemp encourage the use of strains of the plant which are bred for low tetrahydrocannabinol (THC) content or otherwise have the THC removed.

Deutsch: Hygrometer / Español: Higrómetro / Português: Higrômetro / Français: Hygromètre / Italiano: Igrometro
A hygrometer is an instrument used for measuring the moisture content in the atmosphere. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation (the dew point), or changes in electrical capacitance or resistance to measure humidity differences.
Deutsch: Habitat / Español: Hábitat / Português: Habitat / Français: Habitat / Italiano: Habitat
Habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. It is the natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.

Hydraulics (hydraulic) is a topic in applied science and engineering dealing with the mechanical properties of liquids. At a very basic level hydraulics is the liquid version of pneumatics. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the engineering uses of fluid properties.
