👉 Fluid refers to liquids, which are substances that take the shape of their container but maintain a constant volume. The distance or extent to which fluid occupies space is determined by its volume, which is the amount of space it takes up. For instance, a cup of water has a specific volume, and when you pour it, the fluid spreads out to fill the cup's container while maintaining that volume. This property is crucial in various applications, from cooking and cleaning to industrial processes, where understanding the volume of fluid helps in precise measurements and calculations. The distance or extent of a fluid's spread is also influenced by factors like surface tension, viscosity, and the container's shape and size.
