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...

The viscosity of gases depends on the temperature. For some gases the following formula is relevant: µ(T) = µ0 T0 −C T + C T T01.5 where the values of the constants C,T0, and µ0 are found in the le viscosity_of_gases.dat. The temperature is measured in Kelvin. (a) Load the le into a nested dictionary mu_data such that we can look up C , T0 , and µ0 for a gas with name name by mu_data[name][X], where X is ’C’...

The ideal gas law gives the following formula governing the number of moles of a gas in terms of temperature, pressure, and volume: PV n(T, V, P) = 8.31 . T (a) Find the differential dn of n(T, V, P). (b) You use the ideal gas law to count the number of moles of helium gas in a chamber by measuring pressure, volume and temperature (because, you know, gas is invisible). You make measurements, with the following known possible errors...

The ideal gas law states that PV = NkgT where P is the absolute pressure of a gas, V is the volume it occupies, N is the number of atoms and molecules in the gas, and T is its absolute temperature. The constant ko is called the Boltzmann constant and has the value kg = 1.38x10-23J/K. A very common expression of the ideal gas law uses the number of moles, n- N/NA (NA is Avogadro's number, NA=6.021023 per mole). PV...

8. A experiment is performed on an isolated gas. During the experiment, the gas pressure of an isolated gas in a constant volume flask (V=0.500L) was measured using a gas pressure sensor as the temperature of the gas was varied. The pressure vs volume for the graph for the experiment is shown below, as well as the corresponding curve fit generated. NOTE: The gas temperature inside the syringe was a constant 22.5°C during this experiment. i. Express value of the...
