Problem
1. A 5-m3 container is filled with 900 kg of granite (density of 2400 kg/m3). The rest of the volume is air, with density equal to 1.15 kg/m3. Find the mass of air and the overall (average) specific volume.
2. A tank has two rooms separated by a membrane. Room A has 1 kg of air and a volume of 0.5 m3; room B has 0.75 m3 of air with density 0.8 kg/m3. The membrane is broken, and the air comes to a uniform state. Find the final density of the air.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
