With the exception of water, the particles of an object move closer together and become a solid. Being closer together makes the density rise once it becomes frozen but the density won't rise if the temperature is lowered and the object is already frozen. When water freezes, the density lowers, making ice float.

The concentration of matter in an object?
The concentration of matter in an object is called the density.
Will a density of 2.7 float?
Is this the density of a liquid or an object? If this is the density of a liquid and you want to make an object float, than the density of the object should be less than 2.7. If this is the density of an object you are trying to make float, than the density of the liquid should be greater than 2.7.
What happens when an object is dropped into a beaker containing a liquid and then the object drops to the bottom of the beaker?
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
If the density of an object is equal to the density of the fluid in which it is immersed?
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
If you raise the temperature what happens to an object's density?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
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.
What happens to an object's density when it heats up and expands?
The density decreases.
Whether an object will sink or float?
To know this you first need to find the density of the object and the density of the fluid on which the the object shall be kept. If the density of the fluid is more than the object's density then the object will float. The object will sink if the reverse happens.
If you double the volume of an object what happens to the density?
It is halved.
If you add pressure to an object what happens to its density?
the density will increase because there will be less space
WHAT happens to a solid object with a density that is less than the density of water when it is placed in water?
It floats
What happens to the density of an object when you break it in half?
Assuming the object is the same straight through - nothing.
What happens to an object in water if its density is less than that of water?
it will float
What happens to an object if it has a density that is less than 1 gram?
It floats
Does density effect the temperature of liquids?
Yes it does affect, the denser the substance is, the lesser the temperature needed for it to be frozen . Hence . Density of a substance is indirectly propotional to the temperature it needs to be frozen.
What happens to the density of a object if you cut it in half?
The density stays the same. The reason why is because the density of something is mass divided by volume, so if you cut the object in half, it will not change at all. :) ((and yes the other answer was gibberish lol.))
Does the mass of a coin affects it's density?
It can; density is the mass of an object divided by its volume. Increasing its mass could increase its density--it depends on what happens to the volume as well.
