Question
Give an example of a physical and a chemical reaction.
Answers
GPT 3.5
Physical reaction: Ice melting into water. In this process, the substance remains the same (H2O) but changes its physical state from a solid to a liquid.
Chemical reaction: Combustion of methane. When methane (CH4) reacts with oxygen (O2) and ignites, it undergoes a chemical change resulting in the formation of carbon dioxide (CO2) and water (H2O). This reaction releases energy in the form of heat and light.
