Answer 1

Answer:

Any object that is in water has some buoyant force pushing up against gravity, which means that any object in water loses some weight. If the object displaces an amount of water equal to its own weight, the buoyant force acting on it will be equal to gravity and the object will float. An object will sink in water if it is made up of particles that are more tightly packed together than the particles in water. If the brick has less dense than it will float. If the brick has greater mass, it will sink inside water.
