A closed system containing 3.4mols gas of oxygen is initially at a temperature of T1 = 22°C, and pressure P = 101325Pa. Note: Oxygen gas consists of diatomic oxygen molecules that have a molar mass of 32. Remember that the molar mass is the mass of Avogadro's number (NA = 6.02 × 1023) of particles. a) The temperature of the gas is increased isochorically to T, = 120°C. What is the new pressure (P,) of the gas? b) What is the volume of the gas? c) The gas now undergoes an adiabatic expansion to a volume of V2 = 0.095m³. What is the new pressure (P3) of the gas? d) What is the rms velocity of one of the oxygen molecules when the gas is at a temperature of T = 120°C?
