$3-$A $0\mathrm{.}1kg$ of R$-410$a of quality $x=0\mathrm{.}5$ and at $-20C.$ Stops are mounted so Vstop $>$ V$1,$ see Fig. The system is now heated to the final temperature $.$ Estimate that $1\mathrm{.}35>$ Vstops $>4\mathrm{.}35$ and $6\mathrm{.}5C>T2>27\mathrm{.}5C.$ And answer the following:$-$

a$-$ State all your assumptions for this process

b$-$ Draw the P$-$v diagram

c$-$ Find the work and heat transfer in the process
