3) This a collection of problems that are unrelated to each other unless specifically stated. a) In a Sm x 10m x 15m room (like room D219) calculate the mass of air if you are told that the temperature is 290 K and that air has an average molar-mass of 28.8 x 10 kg/m'. b) If a car engine takes in air-fuel mixture at 270 K, and this is compressed adiabatically in the "power stroke", calculate the greatest compression ratio (V/V)the engine could have if the gasoline used ignites at 680 K. What will the pressure be after compression, if the initial pressure is 1.0 atm. Explain clearly! c) Do the calculations of part (b) if you are using high-octant gas, with an ignition temperature of 770 K.

(a) People often think of humid air as "heavy." Compare the densities of air with 0% relative humidity and 100% relative humidity when both are at 1 atm and 30 . Assume that the dry air is an ideal gas composed of molecules with a molar mass of 29.0 g/mol and the moist air is the same gas mixed with water vapor. (b) As discussed in the chapter on the applications of Newton's laws, the air resistance felt by projectiles such as baseballs and golf balls is approximately FD=CpAv2/2 , where p is the mass density of the air, A is the cross-sectional area of the projectile, and C is the projectile's drag coefficient. For a fixed air pressure, describe qualitatively how the range of a projectile changes with the relative humidity. (c) When a thunderstorm is coming, usually the humidity is high and the air pressure is low. Do those conditions give an advantage or disadvantage to home-run hitters?
