C) produce additional ER. D) undergo cell division. E) produce replacement lysosomes. 20) Rough endoplasmic reticulum A) contains ribosomes for protein synthesis. B) creates an enormous surface area for cell metabolism C) contains a compartment to transfer and modify products of metabolism D) all of the above 21) The function of mitochondria is
True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.
Liquid oxygen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below â130Â°F (â90Â°C). Liquid oxygen has a boiling point of â297Â°F (â183Â°C). Because the temperature difference between the product and the surrounding environment is substantialâeven in the winterâkeeping liquid oxygen insulated from the surrounding heat is essential. The product also requires special equipment for handling and storage.
