question 4\nchoose the chemical change from the following options\nflattening a piece of dough\nadding ice cubes to a drink\ngeneration of heat from the decomposition of methane\nmaking shapes with paper
Answer
Brief Explanations:
A chemical change results in the formation of new substances. Flattening dough, adding ice - cubes to a drink, and making shapes with paper are physical changes as they only change the physical form and not the chemical composition. The generation of heat from the decomposition of methane is a chemical change because methane decomposes into other substances during the process.
Answer:
Generation of heat from the decomposition of methane
