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

The summit of chimborazo, in ecuador, which is at a distance of about 6,384 km from the earth’s center. the bottom of the mariana trench, in the western pacific ocean, which is nearly 6,370 km from the center of the earth. on the surface of earth on the equator line.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Four 5-gram blocks of metal are sitting out in the sun and absorb the same amount of heat energy. use the following specific heat capacity data to determine which block will increase its temperature the most.
