**Density and Buoyancy HyperPhysics Concepts**

Density plays a crucial role in Archimedes’ principle. The average density of an object is what ultimately determines whether it floats. If its average density is less than that of the surrounding fluid, it will float. This is because the fluid, having a higher density, contains more mass and thus more weight in the same volume. The buoyant force, which equals the weight of the fluid... for a totally submerged object of any size, shape, or density BVgw=? fluid fluid fluid= BV==? fluid fluid fluid g w Totally Submerged Object mg = ? objectV objectg For completely submerged object: V object = V fluid displaced If ? object < ? fluid, mg < B If ? object > ? fluid, mg > B Floating Object If ? object < ? fluid, mg < B when object is fully submerged F net= B - F g > 0

That if you change the size of an object it changes the density. That the object has to be broken into identical halves for the densities to be the same. These are the results of measuring the mass and volume of one half of the clay ball.... So then if that distilled waters density/specific gravity were to change say to 1.010, would my new apparent weight of the object be 61.15 grams? My math is not solid in this. I'm basically using ratios in order to produce these answers.

**How do we weigh objects in space? (Beginner) Curious**

An items density is its mass divided by its volume. So if you change the shape and the mass and volume remain the same the density does not change but if you change the volume and/or mass then the density will change. how to cook basa in oven • The density of an object can change if either the mass or volume of the object is changed. • Fluids, such as water, have a certain density. • If an object is more dense than water, it will sink; if it is less dense than water, it will float. Density?Prior Knowledge for

**Relative density Wikipedia**

Changing the shape does not change its mass or volume, so density remains the same. Density is an intensive property. This means that regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density. how to change car battery toyota corolla 18/09/2006 · Best Answer: Density is mass divided by vol mass/vol=density g/cm cubed mass is the weight of the object in grams. volume can either be calculated by multiplying side by side by side of the object or you can measure the about of water displaced when the object is submerged.

## How To Change The Density Of An Object

Intensive properties are those that do not change regardless of the quantity of the sample. Mass and volume, the quantities used to determine density are extensive properties because they are dependent on (and change) with the quantity of sample.

- Density equals the mass of the object divided by its volume; D = m/v. Objects with the same mass but different volume have different densities. Summary. Students use the water displacement method to find the volume of different rods that all have the same mass. They calculate the density of each rod, and use the characteristic density of each material to identify all five rods. Then students
- So yes, two objects of the same substance, but with a difference size and/or shape can have the same density, it all comes down to the weight, the volume and the temperature to determine your density, that is assuming your object isn’t hollow of course.
- The density of something is just the mass divided by the volume: D = m/V The mass you can measure on a balance or a scale, and the volume is the amount of space the object occupies.
- So yes, two objects of the same substance, but with a difference size and/or shape can have the same density, it all comes down to the weight, the volume and the temperature to determine your density, that is assuming your object isn’t hollow of course.
