Question 1 • DRHS GA-GSE Environmental Science

Mohammed listed the steps that occur when a solar cell generates electricity.1: Solar energy is absorbed by the cell.2: Free electrons move to the front of the cell.3: Electrons begin to move.4: Electrons flow as electricity.Which best explains how to correct Mohammed’s error?

Answer
A
Switch steps 2 and 3.
B
Switch steps 3 and 4.
C
Move step 1 to appear after step 4.
D
Move step 4 to appear after step 1.

Explanation

First, the cell absorbs solar energy, which gives electrons energy to begin moving. Those moving electrons are then directed toward the front of the cell, where their flow through an external circuit produces electricity. Mohammed put the electrons’ movement to the front before they began moving, so the correct fix is to switch steps 2 and 3.
