How will the pressure change if a sample of an ideal gas in a rigid 2.0 L container initially at 250 °C is cooled to -142 °C? • The final pressure will be 1/4 of the original pressure. The final pressure will be 1/2 of the original pressure. The final pressure will be the same as the original pressure. The final pressure will be 4 times the original pressure. The gas pressure is reduced to zero The final pressure will...
4. Suppose we change the pressure of an ideal gas at constant temperature. How is the corresponding AG related to its AS for the same process? For example, are they proportional to each other, and - if so - what is the proportionality constant?
A sample of ideal gas at room temperature occupies a volume of 31.0 L at a pressure of 862 torr. If the pressure changes to 4310 torr, with no change in the temperature or moles of gas, what is the new volume, V2? Express your answer with the appropriate units. ► View Avallable Hint(s) V2 = 6.20 L Submit Previous Answers Correct Part B If the volume of the original sample in Part A (P1 - 862 torr. Vi =...

Problems 1. According to the Ideal Gas Law, which of the following is/are correct for a gas cylinder of fixed volume filled with one mole of oxygen gas? Please explain each one. a. When the temperature of the cylinder changes from 15 °C to 30 °C, the pressure inside the cylinder doubles. b. When a second mole of oxygen is added to the cylinder, the ratio T/P remains constant. C. An identical cylinder filled with the same pressure of hydrogen...
4.(20pts) Valves closed He (ideal gas) (Flask on left) V 2.50 L P 425 torr Ne (ideal gas) (Flask in middle) V 7.00 L P 677 torr Flesk on Right V 3.00 L P 0 (vacuum) When the valves are open, the gases will mix. Assuming that the temperature is constant, what is the final total pressure in torr? Hint: First compute the partial pressures of each gas after it expands to fill the entire space after the valves are...
