What else can I help you with?
What two forces determine whether an object floats or sinks?
Buoyancy and pressure determine whether the object floats or sinks.
How does the volume of an object affect whether it sinks or floats?
Whether an object sinks or floats is determined by its density in relation to the density of the fluid it's in. If the object is less dense than the fluid, it will float; if it's more dense, it will sink. The volume of an object alone doesn't affect whether it sinks or floats; it's the relationship between its volume and its overall density that determines its buoyancy.
How do you use mass and volume to determine density and why is this an important property?
Density is mass divided by volume. It is important because it is a measure of how tightly packed the mass of an object is. For example, density will tell you whether something floats or sinks.
How do you determine the volume of an irregularly shaped object that floats?
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
Why do some float and others sink?
Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume
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.
Does mass determine an object will float or sink?
No. A toothpick and a tiny stone both have small mass, but one floats and the other sinks. A passenger ferry and a large boulder both have large mass, but one floats and the other sinks. It's not the mass that determines whether the object will float. It's the ratio of its mass to its volume ... the number known as the object's "density".
Does mass determine whether an object will float or sink?
The density of the object (mass/volume) compared to the density of the liquid.
How do you get the volume of something that floats?
To find the volume of something that floats, you can measure the amount of water it displaces when submerged. The volume of water displaced is equal to the volume of the object. This can be calculated by measuring the change in water level before and after submerging the object.
How can you use the calculated value for density to determine whether an object is gold?
divide the objects mass by its volume.
How do you find the volume of an irregular object which floats?
If you push it down, you can measure the volume of the displaced liquid.
Does mass alone determine wheter an object will float or sink?
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.
