You are part of the designing team for a new solar thermal power plant. The plant will use thermal energy storage to produce electricity both during the day (when the sun is shining) and at night (when the sun is not shining!). The chosen storage fluid will be a salt, sodium nitrate (NaNO3). The liquid salt circulates through the concentrated solar energy collectors (mirrors) and achieves a temperature of 623 °C. It is then stored in a cylindrical tank that is 9.1 m in height and 24 m in diameter. The salt stored in the tank is then used to

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.

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.
