Problem: A house is built with a concrete slab and a big south facing window. At 100 m2 and 0.1m thick, the slab has a volume of 10 m3 and thus a mass of 24,000 kg. At 6:00 AM, the temperature of the slab is 16°C. The sun shines in through the window and by 2:00 PM the slab temperature is 30°C. Concrete has a specific heat of 960 J/kg K. We know that one Joule (J) is equal to 1 Watt-second (W sec). We also know that there is 3600 second in an hour.
Part A: How much heat was added to the slab? Please give the answer in kWh of heat added.
I need help to find how much heat was added to the slab.
