# Relationship of mass and volume

### What is the relationship between mass and volume known as? | Socratic Formulas are about relationships between numbers. Mass and volume relate to each other through a concept called density. Density is how. Lab 1: Relationship Between Mass and Volume. Faith Eastwood. Natalia Sedykh. Phys. Purpose. What is the relationship between mass and volume for a. 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. However, once you get the hang of it, density is very useful. To get density, divide mass by volume. For example, a lead brick, 5 cm x 2 cm x 10 cm, weighs 1, g. 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.

Space and Volume Volume measures the spatial size of an object. Each lab station should have a balance, a graduated cylinder, a beaker, a spoon, and salt. Groups go to their lab stations with their white board.

### How Are Density, Mass & Volume Related? | Sciencing

Give each group an empty plastic canister such as a film canister into a beaker of water. Why does it float? How can you make the container rest in the water at a different depths? Students should work in their groups to create a plan — they are to write the plan on a white wipe board.

## What is the relationship between mass and volume known as?

Remind them to leave room to record their data they should take measurements to show what they changed and the results. Give a grape to each group. They are to put the grape into a beaker of water. Why does it sink? How can you make the grape float? Students should work in their groups to create a plan — they are to write the plan on a second white wipe board. Remind them to leave room to record their results. The students may come up with other ideas than salt for Part B so you should have a variety of materials available in case the students request it — sand, vinegar, oil, honey, and a spoon with which to stir the materials if needed. How will the teacher help students determine a way to represent, analyze, and interpret the data they collect? Students should use the data tables to come up with a conclusion statement about each part of the lab that answers the questions: What will the teacher do to bring the lesson to a close? How will the students make sense of the investigation? Direct instruction — define density Think-Pair-Share: What is the relationship between mass and volume for an object that has a high density? What is the relationship between mass and volume for an object that has a low density? After sharing, they are to write their answers in their science notebooks.

### Density – a relationship of mass and volume -

Why is it easier to float in the ocean than it is to float in a pool? Feedback to Students The students will be provided feedback during the activities with questions and comments from the teacher. In the case of liquids and solids, the reference material is fresh water. Specific gravity is calculated by dividing the density of a substance by the reference substance's density. For example, gold has a density of This yields a specific gravity of This means gold is Buoyancy Whether an object floats or sinks is determined by the downward force of gravity and an upward buoyant force.

If the buoyant force is greater, an object floats. If the force of gravity is greater an object sinks.

## Density – a relationship of mass and volume

The interplay between these forces is related to the density of the object and the density of the fluid it is placed in. If the overall density of the object is greater than the liquid, the object sinks. If the overall density of the object is less than the liquid then the object floats.
