Water vapor initially at 3.0 MPa and 300ºC (state 1) is contained within a piston-cylinder device. The water is cooled at constant volume until its temperature reaches 200ºC (state 2). The water is then compressed isothermally to a state where the pressure is 2.5 MPa (state 3). Sketch this process on T-v and P-v diagrams and determine the specific volume at all three states and the quality at state 2.

An object is 10. cm from the mirror, its height is 3.0 cm, and the focal length is 2.0 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1.33 -1.33 +0.75 -0.75
