Final answer:
The D. Decomposition caused by heat is an example of a chemical property.
Step-by-step explanation:
A chemical property is a characteristic of a substance that becomes evident during a chemical reaction or chemical change. It describes how a substance interacts with other substances, undergoes transformations or exhibits specific behaviors, such as reactivity, flammability, or the ability to corrode.
Out of the options given, decomposition caused by heat is an example of a chemical property. When a substance decomposes due to heat, it undergoes a chemical change, resulting in the formation of new substances. It is a process where a substance breaks down into simpler components due to exposure to heat. Elevated temperatures cause the substance to undergo chemical reactions, leading to the breakdown of molecular bonds and the formation of new compounds or elemental constituents.
