REAL GASES n=1 mol of real gas is in a container with a volume of v=0.25lt. The pressure of the gas at T1=300K temperature is p1=90atm, and at T2=350K the pressure of the gas is P2=110atm. Find the Vanderwaals constants (a and b) for this gas.
A gas condensed in a cylinder with a nozzle is initially at p_1=2000 Pa, V_1= 2.0 l, and t_1=300 K. a) If the volume decreases to 0.50 L while the temperature remains low, what is the new pressure?b) If in a) the temperature increases to 400 K when the volume changes, what will be the new pressure?
0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. The gas then undergoes an isobaric process to a temperature of 260°C. What is the final volume of the gas, in liters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

The gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV = nRT, where n is the number of moles of the gas and R = 0.0821 is the gas constant. Suppose that, at a certain instant, P = 7.0 atm and is increasing at a rate of 0.15 atm/min and V = 13 and is decreasing at a rate of 0.17 L/min. Find the rate of change of T with respect to time (in K/min) at that instant if n = 10 mol.(Round your answer to four decimal places.)
