The viscosity n of a glass varies with temperature according to the relationship Qvis n = A expo RT where Qvis is the energy of activation for viscous flow, A is a temperature-independent constant, and R and T are, respectively, the gas constant and the absolute temperature. A plot of In versus 1/T should be nearly linear, and with a slope of Qvis/R. Using data taken from the figure below, make such a plot (i.e., In n versus 1/T) for...

Find P air and V air ..
Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...
