Nitrogen (N2) gas within a piston-cylinder assembly undergoes a compression from P1 = 0.2 MPa, ?1 = 2.75 m3 to a state where P2 = 2 MPa. The relationship between pressure and volume during the process is P?1.35 = constant. For the N2, determine (a) the volume at state 2, in m3, and (b) the work in k

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
