Extrinsic properties are characteristics of an object that depend on its external conditions or environment rather than its internal structure. For example, the color of a leaf can change based on the amount of sunlight it receives, illustrating how external factors influence its appearance. These properties can include aspects like temperature, mass, and volume, which can vary depending on the surrounding conditions. For instance, the weight of an object can change if it is taken to a different planet due to variations in gravity, highlighting how extrinsic properties are not inherent to the object itself.
