At a depth of 10.9 km, the challenger deep in the marianas trench of the pacific ocean is the deepest site in any ocean. yet, in 1960, donald walsh and jacques piccard reached the challenger deep in the bathyscaph trieste. assuming that seawater has a uniform density of 1024 kg/m3, approximate the hydrostatic pressure (in atmospheres) that the trieste had to withstand.

An engine undergoes a cycle as shown in the diagram. during a complete cycle the work done by the gas is 28.5×103 j and the energy transferred thermally out is 99.4×103 j. there are 1.5×1024 gas molecules and they have three active degrees of freedom. 6. (6 pts) during which process(es) is energy transferred thermally into the gas? a. 1→2 b. 2→3 c. 4→1 d. 1→2 and 4→1 e. none of the above
