Consider two separate containers: container A holds 65.3 g of carbon dioxide gas, container B holds 48.2 g of oxygen gas. The pressure of both gases is 1 bar and the temperature is 298.15 K. Both gases can be treated as ideal gases. Parta) Determine the sum of the entropies of the gases in both separated containers. Part b) Calculate the total entropy of the gas mixture, which is obtained after mixing both gases in one container, while maintaining a constant temperature and pressure. Part c) The gas mixture from part b) is expanded in an isobaric process until its volume has increased by a factor of 2.5. Calculate the entropy of the gas mixture after this process is completed.

A few moles of nitrogen (N₂) gas. Change The ammonia condenses to a liquid at a constant temperature of -8.0 °C. The nitrogen is cooled from 78.0 °C to 3.0 °C while the volume is held constant at 2.0 L. The nitrogen is heated from -16.0 °C to 12.0 °C and also expands from a volume of 1.0 L to a volume of 10.0 L.
