Read the questions carefully before answering. Box or indicate your final answers when solving and draw your diagrams cleanly or use correction tape/fluid. Use the steam tables provided and DO NOT ROUND the values from the steam table. Use 4 decimal places when solving and use 2 decimal places for final answers only. Draw the TS diagram with proper placement and label of points when required.
