Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
Objects float in water because water has an?
Objects that float in water have a lower density than water. -anonymous18_K
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
Why does oil float on the water?
Because the specific gravity of oil is lower than that of water. The density of water is 1 g/cm 3 and since the density of oil is less than 1 g/cm 3 it will float. if the density was more than it would sink.
Why Does an aluminum can float on water but an aluminum pole does not?
Because the overall density of a can is less than the density of water, a solid aluminium pole has a density greater than water
Does salt water have a lower density than water?
Yes, fresh water has a slightly lower density than salt water.
Does oil or water have a lower density?
Oil floats on water, and has a lower density.
When do you say that a substances has lower density than water?
A substance has lower density than water when it floats on water. This indicates that the substance is less dense than water.
How is water density affected by freezing?
The density of ice is lower than the density of water.
Why snow floats on water?
The density of snow is lower than the density of water.
What can you infer about density of a substance floats in water?
If a substance floats in water, it is less dense than water. This means that its mass per unit volume is lower than that of water. Substances with lower density will float on top of substances with higher density.
When water freezes what causes it to float?
The density of ice is lower than the density of water.
Why do your pickled eggs float?
The density is lower than the density of water.
What can you infer about the density of a substance if a block of that substance floats in water?
If a block of substance floats in water, it means that the substance is less dense than water. This indicates that the density of the substance is lower than that of water, which has a density of 1 g/cm³.
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.
Will an object with a larger density than water will float in water?
No, an object with a larger density than water will sink in water. Objects float when they have a lower density than the liquid they are placed in.
What does a solid block with a lower density than water do in a container of water?
A solid block with a lower density than water will float in a container of water. This is because the buoyant force acting on the block is greater than its weight, causing it to rise to the surface and float.
