A solid is any piece of matter that has a definite shape and volume. A liquid has no fixed shape but does have a definite volume. This means that you can drop a solid and, depending on how solid it is, it will keep its shape. If it is highly plastic then it may lose its original shape and be reshaped into another one by the force of the fall. If it is highly elastic it may lose its shape momentarily but then regain it. If it is very brittle it may break into a great many pieces none are lost but it has taken on a new, fragmented shape. A solid with great strength is unlikely to be affected by being dropped. Pour a liquid and it will spread out into an irregular shape. A liquid that has a high viscosity will spread out far more slowly than a liquid with a low viscosity. When we pour a liquid none of it is lost (the volume is the same), it has simply taken a different shape. If we heat a solid it may well turn into a liquid.
