Which of the following is true when a rock sinks in water?
Things sink in water when their density is greater than that of water. Water has a density of 1000 kg/m3, rock exceeds this by a significant amount. The principle at work is that things sink if they water tey displace weighs less than the mass of the object.
If a rock with less mass and volume than a body of water how is it possible that it has a greater density and can sink?
Body of water has large mass and volume. Rock has got less mass and volume. But still the rock sinks in the water. The reason is very simple. Density of the rock is more than water. Mass upon volume of the rock is more than water. So rock sinks in the water. That means rock is heavier than water, if the volume of both is same. Alternately the if you take the same mass of both, rock and water, volume of the rock is lesser than that of water.
How does the density of a rock affect its ability to float?
If the density of ANY object is less than 1.00, then it will float in fresh water. If the density is greater than 1.00, the object will sink in fresh water. If the object's density is precisely 1.00, it will be "neutrally buoyant" and will neither rise nor sink; it will remain at whatever depth you place it.
Does the density of a rock cause it to sink or float in water?
Density describes mass per unit volume. Pretty much all rocks will sink unless there is air in it
How does density affect the floating and sinking of objects?
Density is a measure of how much mass is contained in a given volume. Objects will float if their density is less than the density of the fluid they are in and sink if their density is greater. For example, a ship floats because its density is less than that of water, while a rock sinks because its density is greater.
Can sedimentary rock?
No sedimentary rock has been shown to have a density less than water.
What type of density does a rock have when floating in the river?
it has less dense than the water

What is the density of 1.3kg of pumice rock?
The density of pumice rock can vary, but on average it is around 0.25-0.55 g/cm^3. To find the density of 1.3kg of pumice rock, you would need to know the volume of the pumice rock. By dividing the mass (1.3kg) by the volume, you can calculate the density.
What type of rock will float on water?
Any with a density less than the fluid into which it is placed. Pumice is a volcanic rock that will sometimes float on water.pumice

How can you determined if a rock can float in water?
You can determine if a rock can float by comparing its density to the density of water. If the rock is denser than water, it will sink. If the rock is less dense than water, it will float. This can be tested by placing the rock in a container filled with water and observing its behavior.
Is there such a thing as a floating rock?
Yes. It's called pumice, an extrusive felsic igneous rock with a density less than that of water.
Can you make a rock float?
A rock could float if its density is less than that of water, as is the rock pumice, or if it is shaped in a manner that would displace an amount of water to sufficiently cause it to float when carefully placed in water.
How can there be a rock that can float?
Floating (on water) happens when the item place in the water is less dense than the water. The density of the rock called "pumice" is less than that of water so pumice floats. Pumice is a volcanic rock made form a lava "foam" it is solidified rock froth and therefore is very light.
Pumice is a volcanic rock that floats Its density is?
With out knowing further knowledge about the rock it is unable to determine the exact density. However, since the rock floats, presumably in water, the density must be less then 1.00g/L.
