passive solar water heating
Can ANYONE DO THIS, I TRIED IT BUT KEPT GETTING A WRONG ANSWER?
A house is designed to have passive solar energy features. Brickwork is to be incorporated into the interior of the house to act as a heat absorber. Each brick weighs 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 2.0 103 gal of water?
2×10^3 gallons of water = 3785.3 x 2.0×10^3 mL of water = 7570000 cm^3 or 7.57×10^6 grams
7.57×10^6 g x 4.18 J/g K= 3.16×10^7 J per deg K
1.8 kg x 1000 g/kg x 0.85 J/g K = 1.53×10^3 J per deg K per brick
3.16×10^7 / 1.53×10^3 = 20650 bricks
20,000 bricks (1 significant figure)
