Throttling Process in a Gas Chamber
Introduction:
In this scenario, a gas chamber is divided into two parts by a partition wall. One side contains nitrogen gas at a pressure of 2 bar and a temperature of 20°C, while the other side contains nitrogen gas at a pressure of 3.5 bar and a temperature of 35°C. The chamber is rigid and thermally insulated from the surroundings. When the partition is removed, the gas experiences a throttling process.
Throttling Process:
The throttling process refers to a process in which a fluid undergoes a rapid expansion or contraction without any heat transfer. In this case, when the partition is removed, the high-pressure nitrogen gas will expand into the low-pressure region.
Explanation:
When the partition is removed, the high-pressure nitrogen gas will move towards the low-pressure region. This expansion occurs rapidly and without any heat transfer to or from the surroundings, making it an adiabatic process. Let's analyze the effects of this throttling process on the nitrogen gas:
Effect on Pressure:
The high-pressure nitrogen gas will experience a decrease in pressure as it expands into the low-pressure region. This is because the gas expands to occupy a larger volume, resulting in a decrease in the number of gas molecules per unit volume. Therefore, option 'A' is correct as the high-pressure nitrogen gas will get throttled.
Effect on Temperature:
During the throttling process, there is no heat transfer occurring. As a result, the temperature of the nitrogen gas remains unchanged. Therefore, option 'D' is correct as the internal energy of nitrogen will be conserved.
Effect on Mechanical Work:
When the high-pressure nitrogen gas expands into the low-pressure region, it does work on the surrounding gas molecules. This work is done at the expense of the internal energy of the high-pressure nitrogen gas. Therefore, option 'B' is incorrect as the mechanical work is done at the expense of internal energy, not the other way around.
Conclusion:
In summary, when the partition is removed, the high-pressure nitrogen gas will undergo a throttling process. This process results in a decrease in pressure without any change in temperature. The mechanical work is done by the high-pressure nitrogen gas on the surrounding gas molecules, and the internal energy of nitrogen is conserved. Therefore, the correct answer is option 'A'.
