8. An ideal gas is contained in a balloon. The gas within the balloon has a mass of 5 g and a molar mass of 30 kg/kmol. The balloon has an initial diameter of 20 cm and an initial temperature of 30° C. The gas is expanded through a polytropic process with ? = 1.1. This process increases the diameter of the balloon to 30 cm. Determine the pressure of the gas inside the balloon at the final state.
Note: The total mass within the balloon is constant. Express your final answer in kPa.

An ideal gas (the system) is contained in a flexible balloon at a pressure of 1 atm and is initially at a temperature of 1000.°C. The surrounding air is at the same pressure, but its temperature is 25°C. When the system has equilibrated with its surroundings, both systems and surroundings are at 25°C and 1 atm. In changing from the initial to the final state, which one of the following relationships regarding the system is correct?
