4. A rigid tank with a volume of 2 m has two chambers, each of 1 m in volume, containing gas 1, with v1-0.8 m3/kg and gas 2 with V2 = 1.2 m3/kg. a. If the two gases are allowed to mix, what is the new specific volume? b. After they mix, a piston compresses the gases until the volume of the tank is 0.5 m What is the final specific volume of the mixed gas after this compression process?...

1. The density of air is to be determined by measuring pressure and temperature for insertion in the ideal-gas equation: p=pRT The value of R for air is 287.1 J/kg-K and may be assumed to be exact for this calculation. The temperature and pressure are measured as T = 55 +0.4°C p=125 +0.5 kPa Determine the nominal value for density in kg/m' and its uncertainty using...

please do all parts and show work
The goal of this question is to derive relationships of how the pressure and temperature (main part) depend on the height over the sea level h. To do so, we can consider thin slabs of air, vertically stacked. The temperature and pressure at sea level can be denoted T, and pe. For the numerical parts of this question, you can use a molar mass 29.0 g/mol, specific heat c, = 1.00 kJ/kg and...

Heliox is a helium-oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 7.25 L tank holds helium gas at a pressure of 2206 psi. A second 7.25 L tank holds oxygen at a pressure of 586.5 psi. The two gases are mixed in a 7.25 L tank. If the temperature remains the same throughout the process, what is the pressure of the gas mixture...

In the figure, an initially stationary block of mass m= 3.00 kg begins to descend as a connecting cord unwraps from a pulley. Pulley Block Example 10.8.1 Figure 1 The pulley, which is mounted on a horizontal frictionless axle, is a disk (assumed uniform) of radius R=0.200 m and mass m2 = 8.00 kg. We want the speed v of the block and the angular speed o of...
