Density is a physical property of all materials and represents how much mass the material has per unity of volume. If the density is higher than that of water, the material floats. Lower than it sinks.

Materials sink or float in water based on their density. If an object is denser than water, it will sink; if it is less dense, it will float. The buoyant force of water pushing up on an object counteracts the force of gravity pulling it down.
although the shape of material decides whether it sink or float, it also depends on the material. for eg. an iron plate with hole will sink but a thermocol piece will not. if there is two materials of same shape and type, the one with hole have greater possibility of sinking.
Buoyancy is determined by density. If a material has a lower density than the liquid around it, it will float.
Not every type of materials with holes will sink in the water. Only the materials which has more density than the water will sink.
Yes, a carton can float on water depending on its weight and buoyancy. Factors such as the materials the carton is made of, its size, and how well it is sealed can affect whether it will float or sink. Generally, cartons made of lightweight materials like cardboard have a higher chance of floating on water.
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
The property that causes an object to float in saltwater but sink in freshwater is density. Saltwater is denser than freshwater due to the dissolved salts, so objects that are less dense than saltwater will float in it but sink in freshwater.
Yes, arrowheads made from materials like obsidian, chert, or flint are denser than water and will sink. Arrowheads made from lighter materials like bone or antler may float on water depending on their size and shape.
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
