Does sugar has no definite shape?

Yes, sugar does not have a definite shape in its natural state. It typically exists as small crystals, which can vary in size and shape depending on the type of sugar and how it was processed. When dissolved in a solution, sugar molecules disperse and do not maintain a specific shape. However, when crystallized, sugar can form specific geometric shapes, but these are still not considered "definite" in the same way that solids like metals or minerals are.
