Answer 1

D

Explanation:

Generation of heat can also be classified as a chemical property of matter. Heat generation often indicates that a chemical reaction is occurring. Odor, melting point, and appearance (molecule size) are all physical properties.

(A) odor

Explanation:

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
