1) V = nRT/P
2) You mean internal energy? U = 3/2nRT or average translational KE of an individual particle KE = 3/2kT (k is the Boltzman constant)
3)3/2kT = 1/2mv^2. To get mass look up Argon and find its grams per mole and change to kg.
4) SAme equation with v = 11200
A tank holds 135 moles of argon gas (atomic mass = 6.633521 × 10^-26 kg) at a pressure of 101300 Pa and a temperature of 302K. Recall that the number of gas molecules is equal to Avagadros number (6.022 × 10^23) times the number of moles of the gas
1) What is the volume of the tank?
2) How much kinetic energy is contained in this gas?
3) What is the average speed of one of the argon atoms?
4) The escape speed of Earth is 11200 m/s. What temperature would the argon gas need to have so that the average speed of the gas atoms was equal to this escape speed?
