ProblemH1 (Marks =20 ) [Answer in the space provided, show important calculation steps] The following figure shows a tank fitted with an electrie renistor of negligible mass holds 2kg of carbon dioxide (CO2) gas, initially at 25C,100kPa. Over a period of 10 minutes, electricity is provided to the resistor at a rate of Welec=0.14kW. During the same period, a heat transfer of magnitude 14 kJ occurs from the CO2 gas to its surroundings. The gas in the tank behaves as an ideal gas. The gas constant is R=0,19kJ/(kg.K) and specific heat is Cv=0.70kJ/(kg.K) for CO.[0C=273K] Determine: (a) the final temperature T2 of CO2, in " , and (b) the final pressure P2 of CO2, in kPa
