Solids hold their shape due to their atoms being held tightly together.
A solid matter holds its own shape. The particles in a solid are closely packed together, which allows it to maintain a fixed volume and shape.
A gas is a type of matter that does not have a definite shape or size. Gases will expand to fill the space available to them, taking on the shape of their container.
