33) 0.01 kg of certain ideal gas occupies a volume of 0.003 m3 at a pressure of 700 Kpa. If the gas constant is 0.520 KJ/kg ° K, the temperature is_ °C.

5. At temperature t= 15°C and pressure 0.98 bar, the specific volume of 0.45 m/kg. Subsequently pressure drops to P2 =0.6 bar while the temperature remains constant. Make calculation for the density of gas under the change gas %3D condition.

2) Water in a pressure cooker is observed to boil at 175°C. What is the absolute pressure in the pressure cooker, in kPa?

5. A copper calorimeter can with mass 0.446 kg contains 0.0950 kg of ice. The system is initially at 0.0 C. (a) If 0.0350 kg of steam at 100.09C and 1.00 atm pressure is added to the can, what is the final temperature of the calorimeter can and its contents? (b) At the final temperature, how many kilograms are there of ice, how many of liquid water, and how many of steam? 6. The operating temperature of a tungsten filament in an incandescent light bulb is 2450 K, and its emissivity is 0.350. Find the surface area of the filament of a 150-W bulb if all the electrical energy consumed by the bulb is radiated by the filament as electromagnetic waves. (Only a fraction of the radiation appears as visible light.)

A certain ideal gas has the following properties: Cpo = A + (B/T) where A and B are constants and T is temperature in °K and Cpo has units kJ / K /kg. The gas constant is R = 0.25 kJ/K/kg and the constants A = 1.25, B = 173.8029748. For T₁ = 300 °K and T₂ = 400 °K, determine the change in specific internal energy, (u₂-u₁ ) in kJ/kg. You may NOT assume constant specific heats.

Q5) A mass of 0.1 kg of helium fills a 0.2 m' rigid vessel at 350 kPa. The vessel is heated until the pressure is 700 kpa. Calculate the temperature change of helium (in °C and K) as a result of this heating. [337°C, 337 K]

Answer the highlighted part

An insulated, rigid tank is divided into two equal parts by a membrane. (Figure 1) At the beginning, one part contains 9 kg of nitrogen at 500 kPa and 50 °C, while the other part is completely evacuated.
