Which attributes are considered 'aesthetic properties' of materials?

Aesthetic properties of materials are those characteristics that influence how a material is perceived visually and tactilely. The correct answer includes attributes such as color, texture, and finish. These aspects are essential in design as they contribute significantly to the overall appearance and appeal of a product.

Color affects the visual impact and psychological perception of a material, while texture provides a tactile experience that can enhance or detract from user interaction. The finish can influence the material's surface appeal, affecting both the look and feel of the product. Together, these aesthetic properties play a crucial role in attracting consumers and conveying the intended message or style of the product.

The other attributes listed in the remaining choices, while important for various functional aspects of materials, do not fall under aesthetic properties. For example, weight, cost, and durability primarily relate to the performance and practicality of a material rather than its visual or tactile qualities. Similarly, flexibility, strength, conductivity, density, thermal resistance, and water absorption are all functional properties that focus on how materials behave rather than how they look or feel.
