## How is mass of an object measured?

The mass of an object is measured by use of a balance (not a scale). The balance works by comparing the weight of the object with the weight of a known mass, or set of known masses that have been compared against a standard.

## Which measures the mass of an object quizlet?

A balance measures mass. A scale measures weight, or the force of gravity on mass.

## What is the measure of how much surface an object has?

Area is the measure of how much surface an object has. For most objects, area is calculated by multiplying two lengths together.

## Why doesn’t the density of an object change when you adjust the mass and volume?

Why doesn’t the density of the object change when you adjust the mass and volume of the. objects in this section? Density is an intensive property of the material or substance and depends upon the relationship between the mass and volume. Unless the mass changes in relation to the volume, the density will not change.

## Can you change the density of an object?

The density of an object can change if either the mass or volume of the object is changed. If an object is more dense than water, it will sink; if it is less dense than water, it will float.

## Does shape change density?

Changing the shape does not change its mass or volume, so density remains the same.

## Why does size and shape not affect density?

Even though it may seem as if the clay is more compressed (tightly packed) in the oval than in the hollow square, the spacing between those tiny particles that make up the clay is constant (does not change). Therefore, the shape of a material/substance does not affect its density.

## How can you increase the density of an object?

In general, density can be changed by changing either the pressure or the temperature. Increasing the pressure always increases the density of a material. Increasing the temperature generally decreases the density, but there are notable exceptions to this generalization.

## How do you find the mass and volume of an object?

ρ=mV where ρ is the density, m is the mass and V is the volume.

## What are 2 ways to make the density of an object smaller?

What can change density: 1) Adding or removing mass but not changing the volume. Increasing or decreasing temperature changes the volume but not the mass. Increasing or decreasing pressure will change the volume but not the mass.

## Does higher density mean heavier?

If a substance has a higher density, it is heavier. Likewise a lighter density means it is much lighter. For example, air has a density of approximately 1.225kgm3 .

## Can you use mass alone to predict whether an object will sink or float?

Can mass alone be used to accurately predict whether an object will sink or float? -No, you need both mass and volume to determine its desity to see if it can float. -No, you need both mass and volume to find its density to see if it can float.

## Which is more dense water or oil?

Water is more dense (heavier) than oil so they can’t mix. Oil floats above the water.
