find out the thermal energy change of the system and energy consumption and area necessary by solar cell.

1. 550J of heat energy is transferred to a system that does 400J of work. By how much does the system's thermal energy change?

2. The light energy that falls on the square meter of ground over the course of a typical sunny day is about 20 MJ. The average rate of electric energy consumption in one house is 1.0 kW.

a. On average, how much energy does one house use during each 24 hr day?

b. If light energy to electric energy conversion using solar cells is 5 percent efficient, how many square miles of land must be covered with solar cells to supply the electrical energy for 250,000 houses? Presume there is no cloud cover.
