Consider the proposed design for a steam power plant. The water is boiled and vapor is used to spin the turbine. From the turbine, the vapor is sent directly to the pump driven by the same turbine, and back to the boiler. It is claimed that considering some heat losses and friction losses, the efficiency of this device may approach 80%. Required:
a. Is any law of thermodynamics is violated? If so, which one, and why?
b. How would you this system to avoid the violation?

What three things determine the shape and size of a puddle when water is poured out onto a surface

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
