Air consists of gas molecules that are constantly moving. Compute the kinetic energy of a molecule that is moving with a speed of 500. m/s. Assume the mass of the molecule is 4.60 times 10^-26 kg. Suppose you pour a gallon of water on a plant 10.0 ft below your bedroom window: How much potential energy (ft bf) does the water lose? How fast is the water travelling (ft/s) just before impact, assuming that all the potential energy is converted to kinetic energy? Acceleration due to gravity, g = 32.174 ft/s^2 Density of water = 62.43 lb_m/ft^3 A pressure gauge shows that the pressure in a 2.00 L bottle of Diet Coke is 60.0 psi in Atlanta GA. What is the actual (system) pressure in the bottle.? What would the pressure gauge read if for some reason you took the bottle with you to the top of Mount Everest and measured the pressure.
