- A gas with a volume of 640 mL at a pressure of 2.91 atm is allowed to expand to a volume of 3.58 L. What is the pressure in the container if the temperature remains constant? Be sure to enter a unit with your answer. Answer: .052atm If the pressure of a sample of gas is tripled under constant temperature, what will happen to the volume? Select one: a. The volume will decrease by one-third. b. The volume will triple. c. The volume will be reduced by one-half. d. The volume will double. e. The volume will remain the same. Clear my choice If 173 mL of neon at 39.9 °C is allowed to expand to 422 mL, what must the new temperature be to maintain constant pressure? Express your answer in °C. You do not need to enter units. Answer: 1829.73What is the volume of 67 mol of gas, in the unit of m3, when the pressure is 87 kPa and the temperature is 68°C? Use R = 8.314 J/(K mol) for the gas constant. Be careful with units, and remember that the temperature must be in Kelvin when you use the ideal gas equation.Two containers hold ideal gases at the same temperature.Container A has twice the volume and half the number of molecules as container B. What is the ratio PA>PB, where PA is the pressure in container A and PB is the pressure in container B?
- 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 is held in a container with volume 516 cm3. If the pressure of the gas inside the container is 100 kPa, what is the pressure of the gas, in the unit of kPa, when it is expanded to 733 cm3?

- Two containers of equal volume each hold samples of the same ideal gas. Container A has 3 times as many molecules as container B. If the gas pressure is the same in the two containers, find the ratio of the the absolute temperatures TA and TB ( i.e TA / TB ) . Calculate to 2 decimals.A 0.5 m3 container holds 50 mol of an unknown gas at a temperature of 25 °C. A piston is used to expand the volume of the chamber to 1.0 m3 without changing the temperature of gas. What is the pressure in the container now (in kPa)? The piston is again used to change the volume of the container (without changing the temperature). After doing so the pressure in the container is 496 kPa. What is the volume of the container (in m3)?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 pressure of the gas, in atm? 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.
