Gas. Drifting smoke particles indicate the movement of the surrounding gas. Gas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon ), elemental molecules made from one type of atom (e.g. oxygen ), or compound molecules made from ...
Gaslighting. Gaslighting is a colloquialism, defined as manipulating someone into questioning their own perception of reality. [1] [2] The expression, which derives from the title of the 1944 film Gaslight, became popular in the mid-2010s. Merriam-Webster cites deception of one's memory, perception of reality, or mental stability. [2]
A gas stove is a stove that is fuelled by combustible gas such as natural gas, propane, butane, liquefied petroleum gas, syngas, or other flammable gas. Before the advent of gas, cooking stoves relied on solid fuels such as coal or wood. The first gas stoves were developed in the 1820s and a gas stove factory was established in England in 1836.
The Children's Global Assessment Scale ( CGAS) is a numeric scale used by mental health clinicians to rate the general functioning of youths under the age of 18. [1] Scores range from 1 to 90 or 1 to 100, with high scores indicating better functioning. Some versions omit the range from 91-100, as scores in this range would mean "superior ...
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called Gas Laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
v. t. e. Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor. [2]
e. Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment.
Chemical fuels are substances that release energy by reacting with substances around them, most notably by the process of combustion . Chemical fuels are divided in two ways. First, by their physical properties, as a solid, liquid or gas. Secondly, on the basis of their occurrence: primary (natural fuel) and secondary (artificial fuel).
