Question

question 5 (1 point) which of the following are physical properties? check all that apply 1) a substance undergoes evaporation 2) condensation 3) ammonium chloride solid when heated, goes from solid state to gaseous state. 4) oxidation of copper element to copper oxide 5) medication after expiration date 6) two clear solutions when mixed formed a solid

Explanation:

Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Evaporation, condensation, and a substance changing directly from solid - to - gas (sublimation as in ammonium chloride case) are physical changes. Oxidation is a chemical reaction, medication after expiration involves chemical degradation, and two solutions forming a solid is a chemical precipitation reaction.

Answer:

1. A substance undergoes Evaporation
2. Condensation
3. Ammonium chloride solid when heated, goes from solid state to gaseous state.
