EATS 1011 3.0 Introduction to Atmospheric Science YORK UNIVERSITY FACULTY OF SCIENCE Department of Earth and Space Science and Engineering EATS1011 3.0 Introduction to Atmospheric Science Multiple Choice test 30 minutes in the 10:50-11:20 AM Vari Hall A 26 th January, 2009 Useful quantities that you may need. Permitted Aids: A calculator and a standard dictionary. Answer the questions on the SCANTRON answer sheet provided using a soft pencil. Black or blue ball point pen will not be read properly. Be sure that your name and student number appears on the SCANTRON answer sheet. Universal gas constant R* = 8.3143x10 3 Jdeg -1 kmol -1 The Gas Constant for a molecule of mass, m, R = R*/m (kmole/kg) The Gas Constant for air is 287 J.deg -1 kg -1 Surface area of a sphere of radius r = 4 π r 2 . Circumference of circle of radius r = 2 π r. Volume, V, of a sphere of radius r: V = 3 4 3 r π 1 AU = 1.50x10 8 km. Speed of light = 3.0x10 8 m/s. Density of air at MSL, ρ air = 1.2 kg m -3 . Molecular weight of CO 2 = 44 Gravity on Mars = 3.7 m s -2 p = ρ RT Density of liquid H 2 O: ρ H2O = 10 3 kg/m 3 Solar Constant, E = 1.38 kJ m -2 s -1 . Mean radius of Earth = 6370 km Degrees Kelvin = degrees C + 273 1 year = 3.16x10 7 s. 1 mb = 100 Pascals The scale height, H = RT/g metres Mean acceleration due to gravity on the Earth: g = 9.8 m s -2 The Hydrostatic Law: p(z) = p(0).exp(-z/H) where H is the scale height Wien's Law λ max T = 2.9x10 3 μ m °K Stephan Boltzman Law Flux = σ T 4 J m -2 s -1 Relative Humidity: RH = SVP(T D )/SVP(T)x100% Answer the questions on the SCANTRON sheet provided and not on the test paper.
