6. True. The srtongest winds of a tropical cyclone are found near the surface in the eye wall.
7. True. For an ideal gas, Concentration=mole freaction= volume fraction
8. False. If the concentration is 800 ppmv, the mole fraction is 0.0008 (800/ 1000000)
9. False. When the constituent of a mixture has smaller molar mass thean the mean molar mass, its mass fraction will be smaller than its volume fraction.
10. False. At the height between 20kms- 50kms, the water vapour does not get mixed.
11. True. The mass budget of a constituent, the sources of mass include chemical production and chemical deposition while the sink is chemical loss and emission (output)
