To solve the problem of finding the final temperature of dry air released from a high pressure to atmospheric pressure, we will follow these steps: ### Step 1: Understand the Process Since the air is suddenly released, we can assume the process is adiabatic (no heat exchange with the surroundings). This means that the change in internal energy is equal to the work done on or by the system. ### Step 2: Use the Adiabatic Relation For an adiabatic process involving an ideal gas, the following relationship holds: ...
