1. When the density of an object is less than the density of water, the object floats. This occurs because the buoyant force exerted by the water is greater than the object's weight, causing it to rise to the surface and remain partially submerged.

  2. The density of an object determines its buoyancy in a liquid. If the object's density is less than the liquid's density, it floats because the buoyant force exerted by the liquid is greater than the weight of the object. If the densities are equal or the object's density is greater, it sinks.

  3. Objects with a density less than that of the liquid will float when placed in the liquid. This is because the buoyant force exerted by the liquid is greater than the weight of the object, causing it to rise and remain partially or completely above the liquid's surface.

  4. Density is defined as the mass of a substance per unit volume. It quantifies how much mass is packed into a given volume and is typically expressed in units like kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).

  5. The cork floats in water because its density is less than that of water, allowing the buoyant force exerted by water to exceed its weight, keeping it afloat. The nail sinks because its density is greater than that of water, causing it to be denser and thus sink.
