Acoal-fired plant generates 600 mw of electric power. the plant uses 4.8 × 106 kg of coal each day. the heat produced by the combustion of coal is 3.3 × 107 j/kg. the steam that drives the turbines is at a temperature of 300°c, and the exhaust water is at 37°c. (a) what is the overall efficiency of the plant for generating electric power

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
