Yes, that's correct! Both liquids and gases exert a buoyant force on objects placed in them. This is due to the pressure difference between the top and bottom of the object. Here's a breakdown:

* Buoyancy: The upward force exerted by a fluid (liquid or gas) that opposes the weight of an object immersed in it.

* How it works:

* Pressure: Fluids exert pressure in all directions. The pressure at the bottom of an object submerged in a fluid is greater than the pressure at the top because of the weight of the fluid above.

* Net Force: This pressure difference creates a net upward force on the object. This upward force is called the buoyant force.

* Archimedes' Principle: This principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.

Examples:

* A boat floating on water: The buoyant force from the water balances the weight of the boat, keeping it afloat.

* A hot air balloon rising: The heated air inside the balloon is less dense than the surrounding air, creating a buoyant force that lifts the balloon.
