Transcribed Image Text:A rigid tank with volume of 0.1 m contains 200 gram of nitrous oxide gas
(N2O). The gas was initially at temperature 70°C. As a result of heat loss to the
surrounding, the temperature of the gas in the tank drops until it reaches thermal
equilibrium with the surrounding at 30°C. Assuming the nitrous oxide to behave
as an ideal gas with molecular weight of 44.013 kg/kmol and the universal gas
constant to be 8.314 kJ/kmol.K, determine,
