1. Construct the phase of the substance under the given conditions in the stated diagram. Mark all lines to do it with their values. However, do not put anything more in the diagram than is needed to construct the phase. State what the phase is.
   1. R-134a at 20$\POW9,{\circ}$C and 1 MPa, in the $Tv$ diagram. Put in the pressure first.
   2. R-134a at $-$20$\POW9,{\circ}$C and 100 kPa, in the $Pv$ diagram. Put in the temperature first.

2. Construct the phase of the substance under the given conditions in the stated diagram. Mark all lines to do it with their values. However, do not put anything more in the diagram than is needed to construct the phase. State what the phase is.
   1. Water at 100$\POW9,{\circ}$C and 500 kPa, in the $PT$ diagram. Put in the temperature first.
   2. R-134a at 0$\POW9,{\circ}$C and 350 kPa, in the $Tv$ diagram. Put in the temperature first.
   3. Ammonia at $-$10$\POW9,{\circ}$C and 150 kPa, in the $Pv$ diagram. Put in the temperature first.
   4. Ammonia at $-$10$\POW9,{\circ}$C and 150 kPa, in the $Tv$ diagram. Put in the temperature first.

3. Construct the phase of R-134a at $-$10 F and 18 psia in the $Pv$ diagram. Use the English-units tables only. Mark all lines to do it with their values. However, do not put anything more in the diagram than is needed to construct the phase. State what the phase is. State the specific volume of the substance. Note: use the english units tables in appendix F or G in the far back of the book. No conversion to SI units! In case you do not have a compressed liquid table, you will have to use saturated liquid values. Make sure you get the temperature right!
