How does a lemon battery work and what is the science behind its ability to generate electricity?
A lemon battery works by using the acid in the lemon as an electrolyte to create a chemical reaction that generates electricity. The citric acid in the lemon reacts with the metal electrodes (usually zinc and copper) to create a flow of electrons, which produces a small amount of electrical energy. This process is known as an electrochemical reaction, where the transfer of electrons between the electrodes creates a voltage difference that can be used to power a small device.

What does fuel mean in science?
In science, fuel refers to a material that can be consumed to generate energy through a chemical reaction, typically combustion. Fuels are commonly used in engines, power plants, and other applications to produce heat or electricity. Examples of fuels include gasoline, coal, natural gas, and biomass.
What is the term for the property 'ability to burn' in science?
The term for the property "ability to burn" in science is flammability. This property refers to how easily a substance can ignite and sustain combustion when exposed to a heat source.
What are fluids in science?
In science, fluids are substances that can flow and take the shape of their container. They include liquids and gases. Fluids have the ability to exert pressure and are characterized by their ability to deform under shear stress.
What a Bunsen burner is used for in a science lab?
A Bunsen burner is used in a science lab to generate a controlled flame for heating, sterilizing, or combustion purposes. It is a common tool for conducting experiments that require the application of heat.
What uses chemical energy?
Chemical energy is used in various processes, such as in the human body to fuel cellular activities like metabolism and movement, in automobiles to power engines through combustion, and in batteries to generate electrical energy through chemical reactions. Additionally, chemical energy is utilized in many industrial applications for producing heat, light, and electricity.
