molecules make an object float the airs density has gases that react to substance and then change phase an element has only 1 kind of atom and that atom gets
If the object does not quite float in water, adding salt to the water might make the object float, yes.
Many things can float in water. An object will float based on 2 main factors. They are density and shape. If an object is too dense, it will sink. But why would shape matter? The shape of the object affects how the water is displaced. If the weight of the water displaced is more than the weight of the object that is touching the water, the object will float. So the shape affects how much water is displaced therefore determines if an object will float.
The object would float in the middle if it was in water.
That depends what object you want to float.
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
float
The density of an object determines whether it will float or sink in water. If the object is denser than water, it will sink. If it is less dense, it will float.
An object will float in water if its density is lower than water which means that for an object to float, its density needs to be less than ~1 gram/centimeter^3,
If an object is less dense then water, it will float assuming the object does not absorb the water there by increasing its density.
an object will float on salt water best
An object will float on water if it has less density than water.
Any object that is less dense than water will float.
