Homework Statement
A tank made of a material with negligible heat capacity is connected to a pipeline containing steam at 20 kPa and 250°C. Assume the tank is well insulated and that it has a volume of 1 m3. The tank is filled with steam until the pressure equilibrates, then it is disconnected from the pipeline. How much steam is in the tank and what is its temperature if:
a)the tank is initially evacuated?
b) the tank initially contains steam at 1 kPa and 125°C?
Homework Equations
The Attempt at a Solution
I can't proceed with this problem because I don't know what the conditions are when ''pressure equilibrates''.
