What is Malthusian theory all about? The Malthusian Theory of Population is the theory of exponential population and arithmetic food supply growth. The theory was proposed by Thomas Robert Malthus. He believed that a balance between population growth and food supply can be established through preventive and positive checks. What did Malthus suggest? Thomas Malthus […]
What is the smallest part of an element?
What is the smallest part of an element? atom How many atoms are in a dollar bill? so we just take (1 g/1 dollar)(1 mol/162 g)(6.022 * 10^23 molecules/mol)(21 atoms/molecule) = 7.806 * 10^22 atoms/dollar, which is around 78 sextillion atoms. Do atoms multiply? In the sense that living organisms reproduce, no, atoms do not […]

What is the volume of primitive unit cell of BCC?
What is the volume of primitive unit cell of BCC? Body-centered cubic (bcc) lattice: Primitive translation vectors of the bcc lattice (in units of lattice parameter a) are a1 = 슬-½; a2 = – 슬 a3 = ½-슬. The primitive cell is the rhombohedron. The packing ratio is 0.68, defined as the maximum volume which […]
