Let us use the periodic table, which indicates the relative atomic masses of chemical elements. Hence, the relative atomic mass of hydrogen (Mr) is 1, whereas for helium Mr = 4. Helium is an inert monatomic gas, so M (He) = 10-3*Mr (He) kg/mol = 10-3*4 kg/mol = 0,004 kg/mol. Where do we begin when we are to speak about helium? Right, with the molar mass of helium. It is a well-known fact that this inert gas is the most stubborn of all gases. Its atoms in no circumstances do not want to engage with one another or with atoms of other elements. Exactly the obstinate unwillingness of helium atoms to interact explains why this gas was the last, which yielded to chemists’ efforts and succumbed to liquefaction (helium has the known lowest critical temperature T = 5.25 K).
A Response to Embroidery simply by Ray BradburyThe short story 'Embroidery', written by Beam Bradbury is one, which willcould be classed as a scientific research fiction history with some politicsaspects to it. 'Embroidery' ends in apocalyptic terms, exactly where an atombomb is dropped. Drafted in the 1960's meant that the cold warfare waseven now going on and being hit by an atomic bomb was highly possible. My spouse and ithink that due to this a general target audience reading this account in theperiod it was written would have discovered this tale frightening withthat time the storyline may destination even been slightly debatable.From a feminists standpoint this text message would be looked upon witha great deal of interest. Firstly, the brief story was written by BeamBradbury, a male, so a feminist reader may find it interesting howgirls are described in the history compared to the males. The textprimarily..
