Answer:
Gases:
Gases can be squeezed into smaller spaces when pressure is applied.
Gases can expand to fill any available space.
Gases are light and can move easily.
Gases are used in systems that need quick and flexible movements.
Liquids:
Liquids cannot be easily squeezed into smaller spaces.
Liquids take the shape of the container they are in.
Liquids are heavier and flow more slowly.
Liquids are used in systems that require strong forces and precise control.
How these properties affect their use as fluid power mediums:
Gases are used when we want things to move quickly and easily, like in pneumatic systems (e.g., inflating balloons).
Liquids are used when we need strong forces and precise control, like in hydraulic systems (e.g., operating heavy machinery).
So, gases are good for quick and flexible movements, while liquids are better for strong forces and precise control.
