how does mass affect an object's density?

Density of a quantity of matter is its mass divided by its volume. ... External pressure pushes the atoms or molecules closer together and increased temperature usually expands the volume of the material, pushing the molecules apart. A change in the phase or state of a material usually results in a change in density.

Density is a measure of mass per unit of volume. Density is a measure of mass per volume. ... An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

How does temperature affect the mass of an object? When you heat the temperature the atoms in the object move faster. So that's how the mass of an object changes.

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Apparent density - the mass per unit volume of the particles in a granular material, excluding the voids in the material. ... Bulk density - the mass per unit volume of a bulk of a material, including the air voids between the particles, and inside the particles.

The mass of any object is simply the volume that the object occupies times the density of the object. For a fluid (a liquid or a gas) the density, volume, and shape of the object can all change within the domain with time. And mass can move through the domain.

The mass difference between two objects causes heat transfer. The density difference between two objects causes heat transfer.

What is the difference between density and mass? Check all that apply. ... The mass of a substance is independent of the amount of the substance, while density depends on the amount of the substance. The density of a substance is independent of the amount of the substance, while mass depends on the amount of the substance.

Mass is the amount of matter in a body, normally measured in grams or kilograms etc. Weight is a force that pulls on a mass and is measured in Newtons. ... Density basically means how much mass is occupied in a specific volume or space. Different materials of the same size may have different masses because of its density.

The density of a gas depends directly on the molar mass of the gas. This means that as the molar mass increases, density increases and vice versa.

Density is a calculation of how much matter is squeezed into a given amount of space. It is a ratio—the amount of mass per unit of volume. Scientists define density as the mass of a substance per unit volume. It is the relationship between the mass (or weight) of one unit of a material and the volume of that one unit.

If an object's weight is greater than the buoyant force acting on it, then the object sinks. A given volume of a denser substance is heavier than the same volume of a less dense substance. Therefore, density of an object also affects whether it sinks or floats.

Inertia affects all objects, and all objects have mass. The mass of an objects demonstrates how much matter is within the object. The larger the mass of an object the more inertia it has. Finally, the weight of an object has to do with the the amount of gravity that is being pulled down upon it.

What is the difference between weight and mass? a. Weight depends on density and mass depends on gravity.

Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in, the higher the density. Density can be calculated by dividing an object's mass by its volume.

Because the molecules are in motion, a gas will expand to fill the container. Since density is defined to be the mass divided by the volume, density depends directly on the size of the container in which a fixed mass of gas is confined.

Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
