How do you use the word density in a sentence?
You can find a rock's density in many different ways. That object has a high density and will not float on water.
Does volume alone determine weather an object will float or sink?
No. A very big rock has a great deal of volume- but it also has a great deal of weight. Drop it in water, and it will sink like a........rock. It is the weight per measure of volume that determines density. If the density is less than the liquid, it floats. Greater than the density of the liquid, it sinks.
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.
Can a brick float?
Objects denser than water will sink; objects less dense than water will float. Since aluminum metal has a density of around 2.7 grams per cubic centimeter and water has a density of 1.0, a solid block of aluminum would sink.
How does a stick float and an rock sinks?
The general rule is that an object will float if it has less density than the liquid in which it is placed, or sink if its density is greater.
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.
Will a rock float in water why is it density?
Yes some rocks can float in water. And its determind by density because water density is (8 lbs per gallon and 1 gram per ML) If a rock is lower density then water it floats.
How do you use the word density in a sentence?
You can find a rock's density in many different ways. That object has a high density and will not float on water.
Can metamorphic rocks float?
The extrusive volcanic rock pumice can float on water. Other extrusive volcanic rocks are not so lucky.
Why can you lift a rock in water but a rock will not float?
A rock has more density than water. That's why it drops. Its easier to lift it in water because water's density is greater than that of air, so the net buoyancy of the rock, though still negative, is greater than it is in air.
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

Why don't rocks float?
Because their density is greater than ' 1 '. That means that any amount of rock material is heavier than an equal volume of water. A rock will float in mercury, though.
If the porous lava rock gravel was placed in water what would happen?
Pumice is a porous rock that can float on water. It's density is less tham 1g per cm.
Will something with a density of 68 g per cubic cm sink or float in water?
Sink. Like a rock. Faster than a rock. The density of water is ~1 g/cm3. Anything more dense than that will sink.
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.
