- For this problem, we want to estimate the answer, so our assumptions may be a little unrealistic. Suppose we want to estimate how much air we need to send to a space station, assuming we cannot recycle air. Suppose four astronauts are in a spherical space station. If each of them typically breathes about 500 cm³of air with each breathe, and take 15 breathes per minute (average resting value): a. What is the volume of air you would need in the space station if these four astronauts stayed for a full year? b. If the density of air is 1.25 kg/m³ and it costs (thanks to SpaceX) a mere $100/kg to send objects to the space station, how much money would the astronaut air supply cost?The energy released from condensation in thunderstorms can be very large. Calculate the energy released into the atmosphere for a small storm of radius 1 km, assuming that 1.0 cm of rain is precipitated uniformly over this area."How much does all the air in the world weigh?" Calculate the mass of Earth's atmosphere using the irrelevant space integral. (Hint: Density is shape P(r) = Poe-c(r-R) 1.225 kg/m³ and c = (In 10)/(17 km); the density drops to one-tenth in the 17 km distance. Integrals can be calculated with a suitable program.) (Answer: 5.10¹8 kg, or about 10-4% of the Earth's mass.) when r≥ R.Here R = 6370 km, po =
- Calculating the Number of Molecules in a Cubic Meter of GasHow many molecules are in a typical object, such as gas in a tire or water in a glass? This calculation can give us an idea of how large N typically is. Let’s calculate the number of molecules in the air that a typical healthyyoung adult inhales in one breath, with a volume of 500 mL, at standard temperature and pressure (STP), which is defined as 0 ºC and atmospheric pressure. (Our young adult is apparently outside in winter.)StrategyBecause pressure, volume, and temperature are all specified, we can use the ideal gas law, pV = NkB T, to find NA 5 cubic meter container is filled with 840kg of granite[density is 2400 kg per cubic meter and the rest of the volume is air density is 1.15 kg per cubic meter. Find the mass of air present in the container. choices: a.5.7534 kg. b.5.3475 kg. c.5.5374 kg. d.5.4375 kg need solution, show cancellation and use proper symbol:)A given mass of gas occupies a volume of 180 mL at a pressure of 8, (0) atmosphere. Calculate the volume when the pressure changes to 0.6 atmosphere with constant temperature. How much is the size of twice the mass at a pressure of 0.6 atmosphere at the same temperature?
