Apower plant uses 365 gj/hr of energy from a boiler and extracts 18 gj/hr as work from a turbine and rejects the remaining energy to a large cold resevoir of air (the atmosphere). what is the rate of heat rejection to the atmosphere for this plant? give your answer in gj/hr
what i know is that gamma rays are the shortest, and i am pretty sure radio waves are a type of gamma ray. i also know that uv rays are longer than x-rays. given this information, and the question, i would say uv rays.
the silvered walls
the silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection. the thinness of the glass walls stops heat entering or leaving the flask by conduction. the case surrounding the flask provides additional insulation.
the correct answer is c
d, water vapor. gaseous state would have more kinetic energy, they are moving faster. if you have to compare the same state, then higher temperature would have the higher kinetic energy. but if you have solid and liquid at the same temperature - then liquid would have more.
