The density of an object is constant, therefore, no rock can have less density in water.

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.
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.
What does the word density mean in science?
Density is the mass of a fixed volume of something. Water is the standard, and a mass of 1 gram of water has a volume of 1 cc, so its density is 1. 1 cc of rock has a mass of about 6 grams, so its density is 6. Things which float have a density less than 1.
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.
A rock displaces 1200 ml of water what is the rock's volume?
1200ml = 1200 cm3 unless the rock floats (there are rocks that have density less than 1) in which case the volume of the rock is greater than 1200 cm3 and the mass is 1200 g
Name an extrusive rock with a very low density?
Pumice is an extrusive igneous rock with a density less than that of water.
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
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.
What is the density of 1.3kg of pumice rock?
Since it floats in water it has a density less than 1.00
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.
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.
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.
Is earth floating on water?
no because its density is greater than one ( anything less than one, density wise would float ____________________ Actually, only Saturn "would float"; ie, has a density less than 1. Earth has a density of 5.5 or so, and if there were a big enough bathtub, would sink like the rock it is.
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
