## Why do we need to know volume?

Finding the volume of an object can help us to determine the amount required to fill that object, like the amount of water needed to fill a bottle, an aquarium or a water tank. The volume of an object is measured in cubic units such as cubic centimeters, cubic inch, cubic foot, cubic meter, etc.

## What is a real life example of volume of a cylinder?

The volume of a cylinder is the area of the base times the height. An example of this is a soup can. If the radius of the soup can is 2 inches and the height is 4 inches, then the volume of the can is pi x 2^2 * 4, or roughly 50.24 cubic inches.

## What is the difference between density and volume?

Density and volume are scientific concepts pertaining to physical properties and characteristics of matter. Volume refers to the measurement of the amount of three-dimensional space occupied by an object. Density refers to the mass contained in a substance for a given volume.

## How do we use mass in everyday life?

For example, a ball will have a different weight on the Moon than it would on Earth, but in both cases it would have the same mass. See book on forces for more information about weight. Mass can also be seen as the difficulty of accelerating an object. See book on acceleration.

## Which sample has lowest density?

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

osmium

## What is density in pharmacy?

Pharmaceutical density meters are useful in evaluating the material porosity of a solid drug substance or determining the specific gravity of liquid samples. Pharmaceutical density meters include pycnometers, which measure absolute, envelope, and bulk density.

mercury

liquid hydrogen

## What liquids are more dense than water?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids….How Does It Work.

Material Density (g/cm3)
Pancake Syrup 1.37
Light Corn Syrup 1.33
Dish Soap 1.06
Milk 1.03

Vegetable oil

## What has same density as water?

A 12 pound ball is about the same density as water, an 11 pound ball will float, and a 13 pound ball will sink.

## What is the second heaviest thing in the universe?

In terms of actual weight, the heaviest object ever directly weighed, according to Guinness World Records, is the revolving service structure of the launch pad at the Kennedy Space Center in Florida, clocking in at 4.86 million pounds.

## Has anyone been in a Blackhole?

But if you’re going to try it, you need to know this one small catch. Scientists say humans could indeed enter a black hole to study it. Of course, the human in question couldn’t report their findings—or ever come back.

## What kills you in a black hole?

The point at which tidal forces destroy an object or kill a person will depend on the black hole’s size. For small black holes whose Schwarzschild radius is much closer to the singularity, the tidal forces would kill even before the astronaut reaches the event horizon.

## What is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

## What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death.
