Chemically inert gas is mainly used to fill hot air and party balloons. Balloons filled with it float upwards and this phenomenon is achieved as helium gas is less dense than air Chemically inert In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive. Most Group 8 or 18 elements that appear in the last column of the periodic table (Helium, Neon, Argon, Krypton, Xenon and Radon) are classified as inert (or unreactive). These elements are stable in their naturally occurring form (gaseous form) and they are called inert gases. The noble gases were previously
Phase-out of incandescent light bulbs less than 100 watts, nightlights and shatter resistant bulbs. This effectively banned the manufacturing or importing of most incandescent bulbs of that time. The timeline for these standards was to start in January 2012. By 2020, a second tier of restrictions would become effective, which require all general-purpose bulbs to produce at least 45 lumens per watt (similar to current CFLs). The United States Environmental Protection Agency's Energy Star program in March 2008 established rules for labeling lamps that meet a set of standards for efficiency, starting time, life expectancy, color, and consistency of performance. The intent of the program
