An insulated rigid tank contains 4 kg of argon gas at 450 kpa and 30°c. a valve is now opened, and argon is allowed to escape until the pressure inside drops to 200 kpa. assuming the argon remaining inside the tank has undergone a reversible, adiabatic process, determine the final mass in the tank. 2.46 kg

The final mass of the tank is 2.46kg

Explanation: All shown in the attachment.

Assumptions:

i. Argon is treated as an ideal gas at the specified conditions.

ii. Isentropic relation of ideal gas applies at the given conditions.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
