The average electricity consumption of a house in Gainesville is known to be 1,007 kWh in a month (One month = 30 days). They would like to install solar panels of 29 % efficiency to generate this electricity. Given that the average solar power density in Gainesville is 5.47 kWh/m2/day, how much surface area must the panels occupy? Calculate the result in m2 but do not write the unit. Round off %3D you answer to a whole number (zero decimal place.)
An electrical coil is used to heat 20.0 kg of water in a closed well-insulated vessel. The water is initially at 25°C and 1 atm. The coil delivers a steady 3.25 kW of power to the vessel and its contents, 97% of which goes into heating the water. Determine how long it will take to heat the water to its normal boiling point. Answer in minutes with 3 sig. fig's in decimal format. Show all work starting from the full form of the appropriate balance and justifying any terms being zero or negligible. Cite any data sources used.

The specific heat capacity of water is the amount of energy (in Joules) required to raise the temperature of 1 kg of water by 1 °C; for practical purposes, this is equal to J kg. C about 4186 You put 0.5 L of water in a microwave oven. The water has a starting temperature of 4 °C. The microwave oven is rated at at 1,400 W and efficiency of 53%. If you run the microwave for 35 seconds, what is the temperature of the water when the microwave oven stops? Assume that the density of water is p=1 kg/L. Your Answer:
A mass of 15 kg of air in a piston–cylinder device is heated from 25 to 77°C by passing current through a resistance heater inside the cylinder. The pressure inside the cylinder is held constant at 300 kPa during the process, and a heat loss of 60 kJ occurs. Determine the electric energy supplied, in kWh.
