Climate change, primarily driven by human activities such as fossil fuel combustion and deforestation, poses significant challenges to the environment and society. Rising global temperatures, melting ice caps, and more frequent extreme weather events are among its observable effects. Mitigating climate change requires collective action, including transitioning to renewable energy sources, implementing sustainable land-use practices, and adopting climate-resilient infrastructure. Scientific research plays a crucial role in understanding climate dynamics, predicting future impacts, and informing evidence-based policies to mitigate greenhouse gas emissions and adapt to changing environmental conditions.
Oxygen is a colourless, doorless and tasteless gas. It changes from a gas to a liquid at the temperature of -182.96 degree Celsius the liquid formed as a slightly bluish colour. Liquid oxygen can then be solidified or frozen at a temperature of -2 18.4 degree Celsius.
chemical compound is a chemical composed of many identical molecules (or molecules entities ) composed of atoms for more than one element held together by chemical bonds . A molecule A molecule consisting of atoms of only one element is therefore not a compound. A chemical formula specifies the number of atoms of each element in a compound molecule, using the standard abbreviations for the chemical elements and numerical subscripts .
