Hi everyone,

I cannot for the life of me figure this one out:
"A nonconducting tank of negligible heat capacity and 1m^3 capacity is connected to a pipeline containing steam at 5bar and 370 deg. C. The tank is filled with steam to a pressure of 5bar then the pipeline is disconnected.
a)If the tank is initially evacuated, how much steam is in the tank at the end of the filling process and what is its temperature?
b) If the tank initially contains steam at 1bar and 150 deg. C, how much steam is in the tank a the end of the filling process and what is its temperature?"

Thanks for the help!

What is the signficance of "nonconducting tank of negligible heat capacity"?

If it is initially evacuated, there is no content. If one fills it with steam of 5 bars and 370°C, to a pressure of 5 bars, what can one say about the contents?

In the second question, there is some inital content, at a lower pressure and temperature. One adds steam at 5 bars and 370°C. What can one say about the volume of the tank?
