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?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
