Saturated liquid water at 10.0 mpa is throttled through a partially open valve (isenthalpic process) and discharged into a tank at a pressure 0.1 mpa adiabatically, aergonically, and without any change in its kinetic or potential energy. (note: when the pressure on saturated liquid water is suddenly reduced in an adiabatic aergonic, steady flow process, part of the initial liquid is very quickly converted into a saturated vapor at the lower pressure, with the vaporization energy (heat of vaporization) coming from the remaining liquid. the resulting vapor is called flash steam because the liquid appears to “flash” into a vapor as it expands into the low pressure region). determine:
the exit temperature of the flash steam
the amount of flash steam produced (quality)

What if? physicists often measure the momentum of subatomic particles moving near the speed of light in units of mev/c, where c is the speed of light, and 1 mev = 1.6 ✕ 10−13 kg · m2/s2. based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental si units?

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
