Apiston–cylinder device with a set of stops initially contains 0.6 kg of steam at 1.0 mpa and 400°c. the location of the stops corresponds to 40 percent of the initial volume. now the steam is cooled. determine the compression work if the final state is (a) 1.0 mpa and 250°c and (b) 500 kpa. (c) also determine the temperature at the final state in part (b).

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j. b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
