Priestley’s lasting reputation in science is founded upon the discovery he made on August 1, 1774, when he obtained a colourless gas by heating red mercuric oxide.Finding that a candle would burn and that a mouse would thrive in this gas, he called it “dephlogisticated air,” …They say the candle "uses up" the oxygen by burning. But actually, a candle produces the gas carbon dioxide (CO2) when burning, and CO2 takes up just as much space as the oxygen that went into it. The water level rises, not because the oxygen is "used up", but because the heat from the candle expands the air and forces some of it to bubble out ...Pyrotechnics is the science and craft of creating such things as fireworks, safety matches, oxygen candles, explosive bolts and other fasteners, parts of automotive airbags, as well as gas-pressure blasting in mining, quarrying, and demolition.Hello I was wondering about oxygen stations in the game.
