Why does some food float and some food not?
Whether an object floats or not depends on its density. Density is the amount of mass in a volume, or mass divided by volume. If and object's density is less than that of water, it will float in water, and if an objects density is higher than that of water, it will sink in water. raw material (fishballs will sink down);but it will floats when it is cook. why
What does the weight of an object that floats have the same value as?
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
Wood charcoal is heavier than water yet floats on water?
Because that piece of charcoal is lighter that the water, so it floats.
Why do some objects float or sink in water?
It depends on the density of an object. If the density is higher than the density of the liquid, the it sink. If it's less, it floats.
What causes an object to buoy up?
Water's density is 1.00 g/cm^3. So anything less dense than 1, it floats.
Do an object that floats in water will sink in mercury?
If an object floats in water it will also float in the much denser mercury
What is the property of buoyancy that describes how an object floats on top of water?
The property of buoyancy that describes how an object floats on top of water is called "Archimedes' Principle."
Does an object that floats displace water?
Yes. A floating object displaces its own mass in water.
An object that floats on the surface of water?
the amount of density
How can you determine whether a soild object is more dense or less dense than water?
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
When a obgect floats in water the name of the force pushing is?
The force pushing the object up when it floats in water is called buoyant force. This force is a result of the difference in pressure between the top and bottom of the object in the water, pushing the object upwards.
When an object floats on water there is no gravity acting on it is that true or false?
False. Gravity is always acting on an object, but when an object floats on water, the buoyant force provided by the water is equal to the gravitational force acting on the object, causing it to float rather than sink.
Can the water displacement method be used to calculate the density of an object that floats in the water such as a cork?
Yes, the water displacement method can be used to calculate the density of an object that floats in water. To do this, you would need to measure the volume of the water displaced by the object when it is submerged, and then divide the object's mass by this volume to find its density.
What will happen to an object placed in water if the object's density is less than the density of water?
We both know it floats
If an object floats in water what can you tell about its density?
You can tell that it is less dense than water which has a density of 1 cc
How do you know the density of an object if it floats on water?
If an object floats on water, it means its density is less than that of water. You can calculate the density of the object by comparing its weight to its volume, using the formula density = mass/volume. The density of water is about 1 g/cm^3, so if the object floats on water, its density will be less than 1 g/cm^3.
If an object floats the volume of the displaced water is equal to the volume of the whole object?
Yes, according to Archimedes' principle, when an object floats in a fluid, the weight of the object is equal to the weight of the fluid it displaces. This means that the volume of the displaced water is equal to the volume of the object.
