Solids are a type of matter that have a fixed shape and fixed size. This means they do not change their shape when we move them or put them in a different place. Solid objects feel hard or firm, and they do not flow or pour like liquids. We can touch and hold solids easily. Many things we use every day are solids, such as a book, a chair, a pencil, and a table. Even small objects, like a coin or a toy, are solids. Solids stay the same shape no matter where we put them.
