Q:

What is the difference between mass and volume?

A:

Quick Answer

The mass of an object is the amount of matter it contains while volume is the amount of space it takes up. Mass should not be confused with weight, which is the measure of the gravitational force on an object.

The fundamental unit for mass in the metric system is the gram and in the SI system is the kilogram. The English system does not have a unit for mass; rather, it uses ounces, pounds and tons as units of weight. The metric system uses the liter as its base unit for volume. The base using in the SI system is the cubic meter. In the English system, volume is measure in fluid ounces, cups, pints, quarts and gallons.

  • Q:

    How do you convert milligrams to milliliters?

    A:

    In order to convert milligrams to milliliters, one must know the density of the substance; if the density is measured in milligrams per milliliter, the milligrams of mass of the object being measured are divided by the density of the substance to determine the volume in millimeters. Because density is generally not listed in milligrams per milliliter, it is likely that some calculations must be done to convert the density into the appropriate units.

  • Q:

    What tool is used to measure density?

    A:

    Density is defined as mass per unit volume, so it is necessary to measure both the weight and volume of an object to determine its density. Use a scale to measure the object's weight. A ruler can be used to measure the dimensions of an object and calculate its volume.

  • Q:

    What is the relationship between mass and density?

    A:

    Density and mass are mutually dependent physical properties, with density being equal to the amount of mass per unit of volume of any particular object or substance. The mass of any object depends entirely on its overall density, with denser objects having greater mass, for the same volume, than less-dense objects. The mass of an object with uniform composition changes if pieces are added or removed, but its density remains constant. Meanwhile, barring any melting or evaporation, the density of an object tends to change with changes in temperature, while the mass remains the same.

  • Q:

    What is mass in science?

    A:

    In science, mass is the amount of matter an object has. Newton's second law says that mass is the property of matter that determines the force required to impart a given acceleration to an object.
