A(n) Blank 1 Question 12 system collects and absorbs the Sun's energy, and uses pumps or fans to distribute the collected heat. Image is found in "Using Solar Energy Directly" in Lesson 6. The image above shows an example of such a system. The structure circled in red is the Blank 2 Question 12 , which takes in liquid heated by solar energy. The water is then put in the Blank 3 Question 12 , circled in blue. There are other similar systems, such as the Blank 4 Question 12 , which has an absorber surface painted black to absorb the sun's energy and tubes of fluid that run through the absorber sheet
