  QUESTION 8   Read the extract below, carefully, and answer the questions that follow.   “The word Piezoelectric refers to a material that produces an electric charge when it’s bent or squeezed. The electricity results from pressure and heat building up in the material. Many materials can produce piezoelectricity. Crystals and ceramics both can. Bones and even some protein molecules can be piezoelectric as well. Scientists are looking for ways to use piezoelectricity to do work for us. Piezoelectric materials in clothing could charge our cell phones while they sit in our pockets. Keyboards with piezoelectric keys could harvest electricity as we type. Piezoelectric devices could even use our movements to power themselves as they keep track of our health.” (source: Brookshire, B. 2021. Scientists Say: Piezoelectric.
