Ahorizontal piston-cylinder is used to expand 3 mol of air from 5 bar to 1 bar isothermally at 300 k. if 10 kj of heat is added to achieve this expansion and assuming the gas is ideal, find: (a) the work produced. (b) the entropy generation. (c) the lost work. (d) would the heat required be less, equal, or more if the process were reversible? explain your answer with relevant supporting equations.

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.

What is the force of attraction between the particles in a salt crystal

When svante arrhenius first proposed his acid-base theory, he was a doctoral candidate. his professors thought his ideas were unfounded. within a decade, the arrhenius theory of acid-base was widely accepted and praised within the scientific world. arrhenius defined acids as compounds having ionizable hydrogen and bases as compounds with ionizable a) barium. b) hydronium. c) hydroxide. d) oxygen.
