- Consider two containers with the same volume and temperature. The first container is labelled "Dry" and holds "dry" air = a ratio of nitrogen (N2) and oxygen (O2). The second container is labelled "Humid" and holds "moist" air = the SAME ratio of nitrogen and oxygen, but also contains water (H2O) vapor. According to the ideal gas law, if the pressures are equal, the weight of the gas inside the "Dry" container will beThe density of air at standard conditions (P = 1 atm and T = 20oC) is 1.28 kg/m3. At what pressure is the density 0.64 kg/m3 if the temperature and number of molecules are kept constant?Below the surface of the sea water where the pressure is P=2.45x10^5 Pa and the temperature i 5C, a diver exhales an air bubble having volume of 1cm^3. If the surface temperature of the sea is 20C. What is the volume of the bubble just before it breaks the surface? Assume air in the bubble to be an ideal gas.
- Gas is contained in a 6.00-L vessel at a temperature of 18.0°C and a pressure of 8.00 atm. (a) Determine the number of moles of gas in the vessel. 2.00 mol (b) How many molecules are in the vessel? 1.205 X A mole of objects is equal to how many objects? moleculesThe gas law for an ideal gas at absolute temperature T (in kelvins), pressure P (in atmospheres), and volume V (in liters) is PV = nRT, where n is the number of moles of the gas and R = 0.0821 is the gas constant. Suppose that, at a certain instant, P = 7.0 atm and is increasing at a rate of 0.15 atm/min and V = 13 and is decreasing at a rate of 0.17 L/min. Find the rate of change of T with respect to time (in K/min) at that instant if n = 10 mol.(Round your answer to four decimal places.)Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting.A single astronaut exhales 1.09 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts’ respiration during one week of flight is stored in an originally empty 150-L tank at -45.0°C, what is the final pressure in the tank?
