FIFO Example. You use the first in first out method where you assume the first item you buy is the first item you sell - i.e. items are in a queue You buy the first item for 100 and the second item for 200 - you then sell 1 item for 400. At balance date you would have: Sales of 400 Cost of Sales of 100 Profit of 300 Inventory of 200.
At nanometer size. Any device only a few nanometers in size is nanoscale. Nanotechnology is said to comprise elements less than 100 nanometers in size (100 nm). See nanotechnology and nanometer.
This is not exactly accurate; while atoms are matterâthe smallest pieces of matter you can findâmolecules are the smallest bits of compounds. And particles arenât matter, but the building blocks of it. For example, copper is an element. A copper atom is the smallest piece of copper that exists. Hydrogen is also an element; two hydrogen atoms and one oxygen atom combine to form a molecule of water, which is a compound. While atoms are the tiniest bits of matter, they are made of the sub-atomic building blocks of matterâprotons and electronsârevolving around a nucleus.
