Answer:
what are the items that have been listed?
Answer:
chemical change
Explanation:
burning and cooking are both chemical changes.
Answer:
Yes it is
Explanation:
You use electricity to power the blender itself, then after you power it the potential energy becomes kinetic energy which equals mechanical energy in the blender. So yes, a blender is an example of electrical to mechanical energy.
Ans: B) semiconductor
Photovoltaic cells work by converting light energy to electrical energy. These cells are essentially made of silicon based semiconductors. When photons (light energy) strike the surface of the semiconducting material electrons are let loose. The delocalization of electron creates a flow of charge which produces electricity.
Thus, it is the semiconductor present in a photovoltaic cell which is responsible for converting light to electricity.
