An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.

Aviolently rotating column of air is formed around a region of extremely low air pressure above land. which of these weather conditions is most likely to follow? blizzard cyclone tornado hurricane
