Buoyancy depends upon mainly 2 factors

  • Density of Liquid
  • Volume of Solid Immersed in it


Density of Liquid

More denser the liquid, more will be buoyant force


Sea Water has more buoyancy than Fresh water of rivers and swimming pool

This is because sea water has more density(It contains lots of salts which increases its density)


Volume of Solid Immersed in it

Buoyant force increases if we increase volume of solid immersed in water

If we immerse some only part of solid in water,it will show less buoyancy

If we increase solid immersed,it will show more buoyancy
