Well, a dead body may sink in water then float, because the bodily gases will later bring the body back up to the surface after a little bit of decomposition.
Other than dead bodies, no solid object will sink then float in water.
Submarines might also fit the bill, if your not sticky about the methods.
What else can I help you with?
If an object sinks in water its density is less than that of water?
Yes, that's correct. If an object has a density lower than that of water, it will float. If it sinks, then its density is greater than that of water.
Does a solid block that sinks in a container of water has a lower density than water?
Yes, a solid block that sinks in water has a higher density than water. Density is the mass of an object divided by its volume. If the density of an object is greater than the density of the fluid it is in, the object will sink.
Is floats or sinks in water a physical property?
Yes it is because mass and density are physical properties and density is how you can tell if it is going to sink or float. to find out density, you divide the mass by the volume of an object.
Why does toothpick sink in water?
A toothpick sinks in water because it is denser than water. The density of an object determines whether it will float or sink in a liquid. Since the density of a toothpick is higher than that of water, it sinks when placed in water.
How does the shape of an object affect whether it sinks or floats?
The shape of an object affects whether it sinks or floats by determining its density and displacement of water. Objects with higher density than water will sink, while those with lower density will float. The shape can also impact how much water is displaced, affecting buoyancy.
If an object sinks in water its density is less than that of water?
Yes, that's correct. If an object has a density lower than that of water, it will float. If it sinks, then its density is greater than that of water.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
What happens if an object of higher density is placed in water?
Higher than what ?? If the object's density is higher than the density of water, then the object sinks in the water.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
If an object sinks in water what is its dencity?
More than the density of water.
Does a solid block that sinks in a container of water has a lower density than water?
Yes, a solid block that sinks in water has a higher density than water. Density is the mass of an object divided by its volume. If the density of an object is greater than the density of the fluid it is in, the object will sink.
What is density in everyday terms?
Density is how well an object would float when put into water. Water has a density of 1, so if the object floats, it's density is less then 1. If the object sinks, then it's density is greater then 1.
What is an object with a greater density than water will float in water is it true or false?
False
Is floats or sinks in water a physical property?
Yes it is because mass and density are physical properties and density is how you can tell if it is going to sink or float. to find out density, you divide the mass by the volume of an object.
Why do some objects float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume
What causes something to sink or float?
What causes it to sink or float is the density. The density of water is 1.0. If the object's density is more 1.0 then it sinks, but if the object's density is less then 1.0 then the object will float.
When will an object an object sink?
an objects sinks when its density is more than that of water...... that means when the density of the material is more than 1g/cm3
