The Density calculator computes the mean density (?) of an object based on its mass (M) and volume (V).
INSTRUCTIONS: Choose units and enter the following:
Density(?): The calculator computes the mean density (?) grams per cubic meter. However, this can be automatically converted into other density units via the pull-down menu.
Theis as follows:
Which is heavier, a ton of bricks or a ton of feathers? The foolish person reply "the bricks", but the answer is neither. They are the same weight (mass). HOWEVER, their density is wildly different, because the volume of space to contain a ton of feather is much bigger. Since volume is in the denominator of this equation, the density of the larger volume (feathers) is much smaller.
Density is temperature and pressure dependent, meaning that a change in temperature or pressure will either increase or decrease the density of a substance.
