The initial temperature of three moles of oxygen gas is 240C, and its pressure is 8.00 atm. Determine the nal temperature if the gas is heated until the pressure and the volume are tripled. O 2674 \"C O 216 C 0 621 C O 2400 \"C Question 8 6 pts The Goodyear blimp we usually see hovering above our heads at a football game contains 5500 m3 of helium gas. If there are 1060 kg of gas at an absolute pressure of 1.10 x 105 Pa in the blimp, what is the temperature of the gas? The atomic mass of helium 4.00260 g/mol. ' 0 257K 0 286K 0 275K 0 268K D Question 9 6 pts Suppose a helium atom (atomic mass = 4.003 u) near the surface of the Earth where the temperature is 295 K is moving straight up with a speed that is equal to the root mean square speed. Assume that the atom does not collide with any other atom or molecules. To what height will the atom go up before it comes to rest? (Assume that the acceleration due to gravity remains constant.) O 93700 m 18600 m O 4480 m 9390 m D Question 10 6 pts The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s. At what temperature would iodine molecules (with a molecular mass equal to 253.8 g/mol)have an average speed Vrms equal to the Moon's escape speed
