Agas contained in a piston–cylinder assembly undergoes two processes, a and b, between the same end states, 1 and 2, where p1 = 1 bar, v1 = 1 m3, u1 = 400 kj and p2 = 10 bar, v2 = 0.100 m3, u2 = 420 kj: process a: constant-volume process from state 1 to a pressure of 10 bar, followed by a constant-pressure process to state 2. process b: process from 1 to 2 during which the pressure volume relation is pv = constant. kinetic and potential effects can be ignored. for each of the processes a and b, (a) evaluate the work, in kj, and (b) evaluate the heat transfer, in kj.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:

Astronomers studying the planet of rhombus have detected sedimentary rock on its surface. one astronomer wonders if material in this sedimentary rock used to be in igneous rock deep in rhombus’s interior. can igneous rock become sedimentary rock? explain your answer.
