# Relationship among mass volume and density

### Difference Between Density and Volume | Difference Between | Density vs Volume

Density is defined as mass per unit volume. d = mV. Example: A brick of salt measuring cm x cm x cm has a mass of g. Density is defined as mass per unit volume; mathematically, we would write: or mass m density d relationship between mass and volume of the substance. Mass, volume and density are three of an object's most basic properties. Mass is how heavy something is, volume tells you how big it is, and.

Divide 1, by to get the density of lead, Mass is not completely understood, so it is defined in two very different ways: Inertial mass measures how strongly an object resists acceleration, while gravitational mass measures how strongly an object attracts other things to itself. Strictly speaking, a scale measures weight, but you can usually think of weight and mass as the same thing.

## How are density mass and volume related?

Space and Volume Volume measures the spatial size of an object. Although the formula used to calculate volume depends on its shape and can be complicated, you can think of it generally as width times height times length. Measuring an object's volume can sometimes be easier than calculating it. Putting it into a large container of water and measuring the rise in water level can quickly find the volume, no matter what shape it is.

Objects that have a large mass and small volume have a high density. Objects that have a small mass and a large volume have a low density.

What prior knowledge should students have for this lesson? What are the guiding questions for this lesson?

Why do objects sink? What is the difference between the Diet Coke can and regular Coke can that explains why the diet one floats?

What variables can you change to make the canister rest at different levels in the water, and eventually sink? What variables can you change to cause the grape to float? How will the teacher inform students of the intent of the lesson? How will students understand or develop an investigable question?

Students are in groups of 3. Each chooses a number — 1, 2, or 3. Show a regular Coke and a Diet Coke can both unopened to the class.

In their notebooks, students are to list how the two are similar. After a few minutes, randomly call on students to share their answers the observations can be about the outside of the cans or what they each contain — NO opinions.

Then students create a T-chart to contrast the two.

Again, have the students share answers with the class. Afterwards, tell the students that you are going to place the cans into a tank of water. The students write down what they predict what each can will do.

If a student writes "One will float and one will sink," then tell the student to be specific-identify which can floats and which one sinks. Have the students share their answers with the group and come up with a consensus.

Randomly call on students to share their group's answers. Put both cans in the tank of water.

Students record their observations. As a property, volume is concerned with how much space a particular object occupies.

## The relationship between mass, volume and density.?

Specific shapes like a cube, cylinder, prism, rectangular prism, pyramid, cone, circle, sphere, and other shapes have specific formulas for determining their respective volume. For liquids and gases, the sample substances are put into a container and calculated.

Volume is expressed in units and subunits like cubic meters for solids and cubic liters for liquids and gases. Density and volume have an inverse relationship with each other. If density increases, the effect will be a decrease in volume. In contrast, if the volume increases, density decreases. Both density and volume are physical properties of matter. They are present in the traditional stages of matter, which are solid, liquid, and gas.

Both density and volume have a specific formula regarding solids or regular-shaped objects. In measuring liquids and gases, there is a little deviation from the traditional approach or formula. Density measures the amount of matter present in an object.
