Why is tomato sauce considered as a liquid?

Tomato sauce is considered a liquid because it has a fluid-like consistency that allows it to flow and take the shape of its container. It is primarily composed of water, which is the main component that defines liquids, along with dissolved solids like sugars and acids. The viscosity of tomato sauce is relatively low compared to solids, enabling it to move and be poured easily. This combination of properties aligns it with the characteristics of liquids in culinary and scientific contexts.
