The pvt behavior of a certain gas is described by the equation of state: − = , where is a constant. if in addition is constant, show that: (a) is a function of t only. (b) = const. (here, is the ratio of specific heats) (c) for a mechanically reversible process, − = const.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
