suppose that a substance in a beaker is heated over a burner in a science lab. which observation would most likely indicate that a chemical change has occurred in the substance?\nif the substance is a liquid or solid, an increase in temperature would indicate a chemical change.\nif the substance is a liquid, a change of some of the liquid to gaseous form would indicate a chemical change.\nif the substance is a solid, a change of some of the solid to liquid form would indicate a chemical change.\nif the substance is a liquid or solid, production of an odor would indicate a chemical change.

Answer

Brief Explanations:

A chemical change results in the formation of new substances with different properties. An increase in temperature (first option) can be a physical change like heating water. A liquid changing to gas (second option) is evaporation, a physical change. A solid changing to liquid (third option) is melting, a physical change. Production of an odor often indicates the formation of new substances, which is a sign of a chemical change.

Answer:

If the substance is a liquid or solid, production of an odor would indicate a chemical change.
