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
