Question and answer
Suppose an experiment measures a mass, heats it over a flame without changing its state, measures it again, and finds the mass to be different. Which statement best describes the kind of change that could have taken place? Select one: a. It was a chemical change because the chemical property of the mass changed. b. It was a physical change because the mass melted, going from a solid mass to a liquid. c. It was a chemical change because the mass was lost, most likely as gas. d. It was a physical change because the substance became more dense.
