  • Topic: Buoyancy.

  • Can you drown in the dead sea?

  • Your answer must be yes, right?

  • You must be thinking that anybody who cannot swim will obviously drown.

  • Whether it is a swimming pool or the dead sea.

  • However, that is not 100% true.

  • Confused?

  • Let me explain to you.

  • When an object is partly or wholly immersed in a fluid, an upward force is exerted by the fluid on that object.

  • This tendency of the fluid to exert an upward force on the object is called buoyancy or upthrust.

  • This upward force is called buoyant force.

  • So, do you finally get it?

  • Let me give you one more example.

  • Place a piece of wood in water and push it downwards.

  • What do you observe?

  • It seems like something is pushing the piece of wood upwards, right?

  • Water exerts an upward force on the wood.

  • That is why the wood is getting pushed upwards.

  • This force is called buoyant force.

  • The tendency of water to exert that buoyant force is called buoyancy.

  • Dead sea has a huge amount of salt dissolved in it as compared to any other sea or ocean.

  • The presence of this salt increases density of water present in the dead sea.

  • Higher density leads to greater buoyant force.

  • As the dead sea has very high density.

  • It exerts enough amount of buoyant force to make us float on it.

  • So, if we can float on the dead sea, we are definitely not going to drown in it.
