The person's body does not change density, but when you put a life jacket, you and the jacket can be modeled as one object. The life jacket itself has a very low density, much lower than that of a human. So, when you put on a life jacket, you effectively increase your volume, while mass increases by a much smaller degree. As a result, net density decreases.

How does the density of the metal in the crushed can compare with the metal's density before the can was crushed?
It depends on what you're measuring: the density of the aluminum or the aluminum and the space inside the can. If it's the density of the aluminum only, it doesn't change much. If it's the density of the aluminum and the space inside the can, the density greatly decreases as you are getting rid of the air, and therefore the volume, inside. This also depends on if you are using your foot or a garbage compacter.
How do you identify an object using density?
To identify an object using density, you would need to measure its mass using a balance and its volume using displacement or geometric methods. Then, calculate the density of the object by dividing the mass by the volume. Compare the calculated density to known densities of materials to determine the identity of the object.
How can one determine the air density?
Air density can be determined by measuring the mass of a known volume of air and then calculating the density using the formula: density mass/volume. This can be done using instruments such as a balance and a container of known volume.
How can one determine the density of a substance using temperature and pressure?
To determine the density of a substance using temperature and pressure, one can use the ideal gas law equation, which relates the density of a gas to its temperature and pressure. By measuring the temperature and pressure of the substance, one can calculate its density using this equation.
What physical property of gold can be determined by using mass and volume?
The density of gold can be determined by using its mass and volume. Density is a physical property that describes how tightly packed the material is. Gold has a relatively high density compared to other common metals.
What is a soldiers jacket?
a solodier jacket it is for the solders for using t the out
If Using density how dowe determine if a substance is pure or not?
If a substance is not pure, the density may, or may not, change, compared to the pure substance.
Does the size of an object change an object's density and why?
No. To calculate density you divide mass by volume (d = m/V) If you double the size of something (volume), then you are doubling the amount of it (mass). The whole reason for using density to compare things is because it is a property of the substance that does not change, regardless of quantity.
What is a riddle using the word jacket?
What does a jet pack without a pea wear? JET + PACK - P = JACKET
How do you clean a microsuede jacket?
One way to clean a micro-suede jacket is by using a sued brush. Taking it to a dry cleaners may be necessary if the brush does not clean the jacket.
Density can be determined using?
density = mass+ volume
What are werewolves special abilities?
They can communicate to each other using there thoughts. They also stop aging and they can change into humans.
How do you find relative density of a solid using melde's apparatus?
To find the relative density of a solid using Melde's apparatus, you first need to determine the frequency of vibration of a stretched string driven by a tuning fork. You then immerse the solid in water and measure the change in the frequency caused by the addition of the solid while ensuring that the tension in the string remains constant. The relative density can be calculated by comparing the density of the solid to the density of water, using the formula ( \text{Relative Density} = \frac{\text{Density of Solid}}{\text{Density of Water}} ). This method relies on the relationship between the frequency of vibration, tension, and mass per unit length of the string.

This also depends on if you are using your foot or a garbage compacter.
Can you make a sentence using the word brother's?
I think this jacket is your brother's.
How do you calculate mass using density and volume?
mass= density*volume
How do you identify an object using density?

Then, calculate the density of the object by dividing the mass by the volume. Compare the calculated density to known densities of materials to determine the identity of the object.
