Have you ever noticed that the night sky in winter looks different than the summer? We see constellations at different times of the year - spring, summer, fall, & winter. This occurs because the Earth is orbiting the Sun. ... In summer, we see the opposite (we see Scorpius at night and Orion is in the sky during the day).
Adiabatic.
In thermodynamic chemistry, an adiabatic process is defined as the process in which there is no transfer of heat and mass takes place between system and surroundings. The energy will transfer only in the form of work. The condition is expressed as q=0, which means no heat is transferred. It has various applications in the study of thermodynamics reactions.
Halogen element, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar properties, of which sodium chloride—table salt, or halite—is best known.
