- A room has dimensions of 7.2 m by 5.9 m by 3.2 m. The pressure inside the room is 90,000 Pa and the temperature is 37 degrees C. Another room with the same dimensions and pressure has a temperature of -7 degrees C. If air has a molar mass of 29 g/mol, calculate the mass of air in each room in kg. Which room has the larger mass of air? Answer in kg rounded to the nearest tenths place.A vertical tube that is closed at the upper end and open at the lower end contains an air pocket. The open end of the tube is under the water of a lake, as shown in the figure. When the lower end of the tube is just under the surface of the lake, where the temperature is 37degC and the pressure is 1.0×105Pa, the air pocket occupies a volume of 630cm3. Suppose now that the lower end of the tube is at a depth of 46m in the lake, where the temperature is 17.0degC. What is the volume of the air pocket under these conditions?Saturn's moon Titan has a mass of 1.3452 x 1023 kg , a diameter of 5,150 km, and an atmosphere made mostly of N2 at a constant temperature of -179 degrees Celsius. Assume that the pressure at the surface is 50% more than on Earth. What is your best estimate of Titan's atmosphere's R constant?

- When air expands adiabatically (without gaining or losing heat), its pressure P and volume V are related by the equation PV14 = C where C is a constant. Suppose that at a certain instant the volume is 560 cubic centimeters and the pressure is 81 kPa and is decreasing at a rate of 9 kPa/minute. At what rate in cubic centimeters per minute is the volume increasing at this instant? cm min (Pa stands for Pascal -- it is equivalent to one Newton/(meter squared); kPa is a kiloPascal or 1000 Pascals. )PHET Density X Assignme x → Topic9Wri x y!
