Answer

Brief Explanations:

Chemical changes often produce new substances with different properties. A change in odor usually indicates the formation of new chemical - substances, which is a sign of a chemical change. A decrease in temperature is a physical change related to heat transfer. A change in moisture content is a physical change involving evaporation or condensation. A decrease in mass could be due to evaporation (physical change).
