(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A tank A is connected to a cylinder/piston as shown. The tank has a volume of 100 L and contains saturated vapor R-134a at 30˚C. When the valve is cracked open, the vapor slowly flows into the cylinder B. The piston requires a pressure of 200 kPa in the cylinder to raise it. The process ends when the pressure in tank A has fallen to 200 kPa. During the process, heat is transferred with the surroundings such that the R-134a always remains at 30˚C. Calculate the heat transfer for the process. (101.3 kJ)

2. Relevant equations

E_{2}-E_{1}= Q - W

Work = Pressure * Change in volume

3. The attempt at a solution

i know that the Temp remains at 30˚C throughout the process

volume = 100 L

My question is i never know where to start with these types of problems
