The liquid state of a substance is considered to have what type of shape and volume?

The correct answer indicates that the liquid state of a substance has a changing shape but a fixed volume. In the liquid state, particles are close together but not in a fixed arrangement. This allows liquids to flow and take the shape of their container, leading to the characteristic of a changing shape. However, the volume remains constant regardless of the shape because the amount of liquid does not change when it is moved to a different container.

Understanding the properties of matter, it is important to recognize that solids maintain both a fixed shape and a fixed volume due to their tightly packed particles. In contrast, gases have neither a fixed shape nor a fixed volume, expanding to fill any available space. Thus, the distinction of liquids as having a fixed volume but changing shape is key to understanding the properties of different states of matter.
