What is an item that has definite weight and volume but no definite shape?

The correct answer is liquid. Liquids have a definite weight and volume, which means they possess a specific amount of mass and occupy a specific amount of space. However, they do not have a definite shape; instead, they take the shape of the container they are in.

Gases, while having weight and volume, do not have a definite volume because they expand to fill their container completely. Solids have both a definite weight and volume but also possess a definite shape, making them distinct from liquids. An ice cube, which is solid water, also maintains a definite shape, further differentiating it from the characteristics of liquids. Understanding these properties is crucial in the study of physical states of matter in fields like science and cosmetology, such as when considering the consistency and behavior of various products used in nail technology.
