how can scientists control the flammability of a substance?
Answer
Brief Explanations:
Flammability depends on factors like chemical structure and presence of oxygen. Scientists can change the chemical composition of a substance to make it less flammable, for example by adding flame - retardant chemicals. They can also control the environment around the substance, like reducing oxygen levels.
Answer:
Scientists can control the flammability of a substance by altering its chemical composition (e.g., adding flame - retardants) and controlling the surrounding environment (e.g., reducing oxygen levels).
