Question

Which of the following statements does not describe what happens as a liquid boils? Three 2.0 L containers are placed in a 50 degree C room. Samples of 0.5 mol N_2, 0.5 mol Xe, and 0.5 mol ethane (C_2H_4) are pumped into containers 1,2. and 3, respectively. Inside which container will the pressure be greatest? What volume will 0.875 moles of SF4 occupy at STP? While it is on the ground, a blimp is tilled with 5.66 Times 10^6 L of He gas. The pressure inside the grounded blimp, where the temperature is 25 degree C, is 1.10 atm. Modern blimps are non-rigid which means that their volume is changeable. If the pressure inside the blimp remains the same what will be the volume of the blimp at a height of 2300 m, where the temperature is 12 degree C?

Explanation / Answer

54. a

55. d    (according to gas law p=nRT/V, no difference)

56. The molar volume at STP is 22.4 L/mol

       0.875molx22.4 L /mol = 19.6 L

57. V1/T1 = V/T2 from gas law.

Convert all temperatures in K.

V = 5.41 x106 L
