5. A rigid, closed and perfectly insulated tank containing an ideal gas (R=297J/kg °K k= 1.4 and density = 1.13 kg/m) has a volume of 300 L. The internal energy of the gas is increased by 95 kJ by means of an internal stirrer. If the initial pressure of the gas is 130 kPa, compute for: a. initial temperature of the gas b. final temperature of the gas c. final pressure of the gas d. change in entropy
