How does the density of a substance determine if the substance will float or sink in the water

Answer

The density of a substance determines whether it will sink or float in the water. If the density of the substance is greater than the density of water, then the substance will sink. If the density of the substance is less than the density of water, then the substance will float.

Q: What is the relation between density and whether a substance sinks or floats in the water? A: The density of a substance is what determines if it will sink or float in the water.
Q: How can we determine if a substance will sink or float in the water? A: We can use the following equation: Density of substance = mass of substance/volume of substance. If the density of the substance is greater than the density of water, then the substance will sink. If the density of the substance is less than the density of water, then the substance will float.
