Which one of the following is a chemical property of matter?

Combustibility is a chemical property of matter because it relates to the ability of a substance to undergo a chemical reaction, specifically its ability to react with oxygen and produce heat and light when burned. This property indicates how a substance interacts with other substances at the molecular level, leading to a chemical change.

In contrast, texture, color, and temperature are physical properties. They describe the characteristics of a substance without changing the substance's chemical structure. Texture refers to how a surface feels or appears, color describes the visual aspect of a substance, and temperature measures the degree of heat. While these physical properties can change under different conditions (such as a change in temperature affecting state, e.g., ice melting), they do not involve a chemical transformation or reaction, which is what defines combustibility as a chemical property.
