Read the passage and then answer the question: Lichen is composed of two organisms, an alga and a fungus. The fungus acts like a sponge, holding on to water that the alga needs. At the same time, the alga is constantly turning sunlight into energy, so the fungus, which cannot perform this function for itself, benefits from an **unwavering** energy source. Lichen has, in turn, a relationship with the tree that it grows on. The tree provides lichen with a place to grow, but the tree is unaffected. What is the meaning of "unwavering" as used in the passage? *
1.limited
2.new
3.uncertain
4.steady

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.
