Why is the constant a and b important in the Van der Waals equation of state?
This is the expression valid for van der Waals gases. Calculate the final temperature if the Joule’sfree expansion experiment was carried out to double the volume of 10 mL gas at 25 °C with a) Heb) CO2 molecules. The van der Waals coefficients, a, for He and CO2 are 0.0346 and 3.658,respectively. (Hint: Use equipartition to calculate Cv values and assume three of the vibrations notpopulated in carbon dioxide)
10 molecules of a gas are present in a container maintained at 298 K. What is the probability that all ten molecules will be found simultaneously in one half of the container?
