You can't change the volume of a liquid without adding or removing liquid. Liquids have a fixed volume, meaning they take up a specific amount of space that doesn't change easily.

However, you can change the shape of a liquid very easily! This is because liquids are fluids, meaning they can flow and take the shape of their container.

Here are some ways to change the shape of a liquid:

* Pouring it into a different container: A liquid will take the shape of whatever container it's in. A glass of water is shaped like a glass, while water in a bottle is shaped like a bottle.

* Applying pressure: You can change the shape of a liquid by applying pressure. For example, squeezing a water balloon will change its shape.

* Gravity: Gravity also affects the shape of a liquid. For example, a puddle of water on the ground will spread out due to gravity.
