You are asked to estimate the amount of heat that can be stored overnight in a solar-heated building, which has a storage space of 6 m^3. the solar system uses water with antifreeze in the collector, and there are two options for storing the heat overnight. one option is to use water with an allowable temperature change at 30 degrees with a heat of fusion of 329 kj/l. in both instances, a heat exchanger will be necessary in order to meet building code. discuss the advantages and disadvantages of the two options

Hunter is in lab. he clears a spot on his lab bench to start working. he also puts his lab coat and goggles on. he then identifies where all of the safety equipment is. he notices his station is next to the fume hood, which ventilates the chemicals stored there. the noise of the fume hood was bothersome, so hunter turned it off. which could be an error in his set-up? he should not turn off the fume hood.  he should wait to put on his coat until after the directions are given.  he should wait to put on his goggles until after the directions are given.  he should not sit next to the fume hood.
