A house is designed to have passive solar energy features, brickwork incorporated into the interior of the house act as a heat absorber. Each brick weigh approximately 1.8 kg. The specific heat of the brick is 0.85 J/g-K. How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1.7*103 gal of water?
