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 to delay new energy efficiency standards for light bulbs until 1 January 2014, when it will become illegal to import inefficient incandescent lighting across the country. In December 2011, Ontario Energy Minister [Chris Bentley] confirmed that Ontario is scrapping the five-year-old plan "to avoid confusing consumers". The Energy Star program, in which Natural Resources Canada is a partner, in March 2008 established rules for labelling lamps that meet a set of standards for efficiency, starting time, life expectancy, colour, and consistency of performance. The intent of the program is to reduce consumer concerns about efficient light bulbs due to variable
