Things will sink if they are denser than water.
The weight of the object is either more dense or less dense then the water.
Example: A feather is less dense then water, so it floats. A common stone is more dense, so it sinks.
objects with higher density than water sink, ones with a lower density float
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
it will float
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
An object will float if it is less dense than the water (or other liquid). If it is denser than the water, it sinks.
objects with higher density than water sink, ones with a lower density float
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
Objects that Float in water are less dense than water. Objects that sink are more dense than water. More clearly stated Objects that sink displace less water than their weight of equal measure.
it will float
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
Because some objects are a lot denser than water so the sink and others are less denser so they float
An object will float if it is less dense than the water (or other liquid). If it is denser than the water, it sinks.
objects that are less dense float to the top.
These objects are called with "neutral buoyancy".
Objects sink or float depending on their Mass and density. If the object has a Density LOWER than water, it will float. Higher than water will sink. You can find density by multiplying its Mass times its Volume, there you have its density. Water has a Density of 1, things with lower may sink, only slightly if there isn't much difference.
A submarine
the higher the salinity the more easily an object can float
