Changes of Specific Weight
Unlike density, specific weight is not absolute. It depends upon the value of the gravitational acceleration, which varies with location. A significant influence upon the value of specific gravity is the temperature of the material. Pressure may also affect values, depending upon the bulk modulus of the material, but generally, at moderate pressures, has a less significant effect than the other factors.

Famous quotes containing the words specific and/or weight:
“The permanence of all books is fixed by no effort friendly or hostile, but by their own specific gravity, or the intrinsic importance of their contents to the constant mind of man.”
—Ralph Waldo Emerson (1803–1882)
“The only thing of weight that can be said against modern honour is that it is directly opposite to religion. The one bids you bear injuries with patience, the other tells you if you don’t resent them, you are not fit to live.”
—Bernard Mandeville (1670–1733)
