Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium (He) gas at 220 kPa, 40°C? The other tank initially contains 4.0 R of neon (Ne) gas at 150 kPa, sot. Now the valve is opened, allowing the two gases to mix with each other. Heat transfer occurs during the mixing process. The final equilibrium temperature is 44'C. The specific heats of monatomic gases are independent of temperature. Determine: (a) the final volume of...

A closed, rigid tank fitted with a paddle wheel contains 1.6 kg of air, initially at 200oC, 1 bar. During an interval of 10 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....
