A closed container of volume V = 12 liters holds a mass m, = 0.858 kg of oxygen. It is known that the mass of a liter of oxygen at atmospheric pressure is mą = 0.0015 kg at the same temperature. What is the pressure in the con- tainer? %3D

The bulk modulus of water is B = 2.2 x 10⁹ N/m2. What change in pressure AP (in atmospheres) is required to keep water from expanding when it is heated from 18.8 °C to 30.5 °C? Number i eTextbook and Media Units

A vertical, frictionless piston-cylinder device contains a gas at 600 kPa absolute. The atmospheric pressure outside is 100 kPa absolute. The piston has a diameter of 50 mm. a) Determine the mass of the piston. b) If the mass of the piston is now halved ---- what would be the gauge pressure of the gas?

A 262 kg weather balloon is designed to lift a 1870 kg package. What volume should the balloon have after being inflated with helium in order that the total load can be lifted? (Assume standard temperature and pressure, at which the density of air is pair = 1.29 kg/m3 and the density of helium is PHe = 0.179 kg/m³.) %3D Submit Answer Tries 0/12 Post Discussion Send Feedback
