fireplace that circulutes heat around a house containing 000.0kg of air (cp=1.02k//kgC4C) increasing the average air temperabire of the hoose from 1syCC to 22C. a. Calculate the amount of heat absorbrd by the air in the house. (1) b. What percentage of the wood's eneray weat directly into heating the air (2) c. Brick (in addation to being non-Eaansmable) has a high specifle heat eapacity. Why does it make sense in terms of energy efficlency to surround fireplaces with brickt (2) 32. Hydrochloric acid is used adjust the pH of swimming pools. The optimal pH range for a swimming pool is considered to be 7.2 - 7.8. After filling a pool with 56700 L of well water, the pH is found to 8.2. What minimum volume of 0.100MHCI is needed to get the pool's pH to the optimal range? (4)
