At 0oC and 1 atm, the viscosity of hydrogen (gas) is 8.55x10-5 P. Calculate the viscosity of a gas, if possible, consisting of deuterium. Assume that the molecular sizes are equal.
Indicate the correct option for the velocity distribution function of gas molecules:a) its velocity cannot be measured in any other way due to the small size of the gas moleculesb) it is only used to describe the velocity of particles if their density is very high.c) it describes the probability that a gas particle has a velocity in a given interval of velocitiesd) it describes other magnitudes, such as pressure, energy, etc., but not the velocity of the molecules
