Draw a diagram for each of processes (isothermal, isobaric, isochoric) in variables (P, V), (P, T) and (V, T). Express density of an ideal gas using the equation of state: PV = n/M RT. Explain every step. One mode of oxygen gas is at a pressure of 6.00 and a temperature of 27.0 degree C. If the gas is heated at constant volume until the pressure triples, what is the final temperature? If the gas is heated...
