006 10.0 points 3 The density of gasoline is 730 kg/m³ at 0°C. How many extra kilograms of gasoline are obtained when seven gallons of gasoline are bought at 0°C rather than at 18°C (tempera- ture at the filling station)? One gallon of gaso- line occupies 0.0038 m³ and gasoline's volume expansion coefficient is 0.00096 (°C)-¹. Answer in units of kg.
009 10.0 points 3 A room of volume 101 m³ contains air having an average molar mass of 40.8 g/mol. If the temperature of the room is raised from 10.3°C to 38°C, what mass of air will leave the room? Assume that the air pressure in the room is maintained at 54.9 kPa. Answer in units of kg.
012 10.0 points A gas is at 1 °C. To what temperature must it be heated to double the rms speed of its molecule? Answer in units of °C. MAPAPRAS S 013 10.0 points Gaseous helium is in thermal equilibrium with liquid helium at 7.1 K. The mass of a helium atom is 6.65 x 10-27 kg. Boltzmann's constant is 1.38066 x 10-25 J/K. 23 Determine the most probable speed of a helium atom. Answer in units of m/s.
