A20.0 m3 tank contains steam at 300 °c and 15.0 bar. the tank and its contents are cooled until the pressure drops to 2.5 bar. some of the steam condenses in the process. how much heat was transferred from the tank? what is the final temperature of the tank contents? how much steam condensed? (20 points) – note. to solve this problem, you will need to assume volumes are additive.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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.
