In certain parts of the world, pressurized water from beneath the surface of the earth is available as a source of thermal energy. to make steam, the "geo-thermal water" at 180oc is passed through a "flash evaporator" that that operates at 1 atm pressure. two streams come ot of the evaporator, liquid water and water vapor. how much water vapor is formed per kg of geothermal water? is the process reversible? assume that the water is incompressible. the vapor pressure of water at 180oc is 1.0021 mpa (about 10 atm).

useful constants:

cp (water, liquid) = 4.18 j/(g*k)

cp (water, vapor) = 2.00 j/(g*k)

\deltahvap = 2261 j/g at 100oc

\deltahm = 334 j/g at 0oc

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential. because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential. request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts. ki k i = nothing ev request answerprovide feedback

Talia is manufacturing rolls of wire for hanging pictures. she needs a material that is so that it can easily be pulled into wire without breaking.

The electric field direction is defined by the direction of the force felt by (select one of the following answers): 1. a negative charge. 2. a positive charge. 3. both positive and negative charges.
