Their specific gravity is less than 1
It is inaccurate because whether an object sinks or floats in water depends on its density. Objects with a density greater than that of water will sink, while those with a density less than water will float. Size and weight alone do not determine whether an object will sink or float.
Because it is all about the physical concept of Density . You should say that an object will float if it's Density is lower than the Density of the fluid you choose to put it into . Example. Aluminum will float in Mercury liquid, because it is less dense than Mercury, yet you might refer to Aluminum as a heavy object , depending upon what other substance you are comparing it to.

An object will float when submerged into liquid because its density is less than that of the liquid. As described in Archimedes' Principle, the buoyancy forces on an object will be equal to the weight of the liquid displaced. If the density of the object is less than that of the liquid, the weight of the liquid that would be displaced by the volume of the object will be greater than the weight of the object and the object will float. If the density of the object is more than the density of the liquid it would displace when submerged, the object will sink.
No, salt gets dissolved in water. Fresh water floats above salt water. In places with little mixing (fjords) there can be a several centimeter thick layer of fresh water above the salt water.
well sometimes bcuz how the water is like lets say the oil it wouldn't be good to put objects to float.
Bromine will usually sink in water depending on the dose. Let's say you add 1.0mL of Bromine in water. This will sink because it is denser than water. If you add a lesser dose, it might float.
They have different densities. If one liquid ( say water) is mixed with another that is lighter in density ( say oil) the lighter density will float on top. Try it!
A steel needle will float in water as a consequence of surface tension. A boat floats in water because it displaces sufficient air to make its effective density less than that of water. Usually though, solid, spherical objects, for example, will float if they are made of materials that are less dense that water, which is to say that they have less mass per unit volume than water. In ordinary, imprecise language we say things weigh less than water.
because of density, water comes with a weight, lets say 3 tonnes, obviously a human would float straight away but if it was less, lets say 150 kilograms then you would sink until you are at an equal density to the water
It is incorrect to say that heavy objects sink in water because... A big slab of wood is heavy, right? Wood floats. For one example.
Anything heavier than water sinks; anything lighter than water floats. Or, another way to say it: anything with a higher density than water (water weighs about a gram per cubic centimeter), or a higher specific gravity than water, sinks. If the object weighs less than the weight of water that it displaces, then it floats.
