- A hollow container is filled with an ideal gas. The container is designed to maintain a constant pressure by allowing gas to enter or leave as needed. at all times the gas and container are in thermal equilibrium. initially the temperature is 1078 K. then the temperature decreases to 200 K and the volume decreases to .88 times the initial volume. determine the coefficient of volume expansion for the container and the ratio of the final number of moles to the initial number of moles. Please include the units, and round to the fourth decimal point.1. Building on our knowledge of gases: 1.6 mole of CO₂ (g) occupies 3.2 L at T = 300 K. If the gas is compressed isothermally at constant external pressure Pext so that the final volume is 1.2 L, calculate the smallest value Pext can have, assuming that CO₂ satisfies the van der Waals equation of state under these conditions. Calculate the work involved using this value of Pext.A sample of 2.37 moles of an ideal diatomic gas experiences a temperature increase of 65.2 K at constant volume. Find the increase in internal energy if only translational and rotational motions are possible.
- 3-An ideal gas consists of 2.50 mol of diatomic molecules that rotate but do not oscillate. The molecular diameter is 118 pm. The gas is expanded at a constant pressure of 1.79 x 105 Pa, with a transfer of 150 J as heat. What is the change in the mean free path of the molecules?Equal moles of three different ideal gases (A, B, and C) are prepared in separate sealed chambers at different temperatures. The velocity distributions for molecules of the three gases are shown below. The gases have different molecular masses which are not known. Which of the following statements about these gases MUST BE true? Number of Molecules B C Velocity Gas C has the greatest temperature. Gas A has the greatest average kinetic energy per molecule. O Gas C has the greatest average kinetic energy per molecule. O Gas A has the greatest molecular mass. O Gas C has the greatest rms speed. Next.
