10 kg of liquid water is in a container maintained at atmospheric pressure, 101325 pa. the water is initially at 373.15 k, the boiling point at that pressure. the latent heat of water -> water vapor is 2230 j/g. the molecular weight of water is 18 g. 10^3 j of heat is added to the water. a. how much of the water turns to vapor? b. by how much did the gibbs free energy change? c. by how much did the entropy change?

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
