what is specific gravity?

Answer 1

Specific gravity is the ratio of the density of a material to the density of water. The density of water is about 1 gram per cubic centimetre (g/cc). Materials which are lighter than water (specific gravity less than 1.0) will float. Most materials have specific gravities exceeding 1.0, which means they are heavier than water and so will sink. Knowing the specific gravity is important for planning spill clean-up and fire fighting procedures.

Answer 2

The specific gravity is defined as the ratio of specific weight of the material to the specific weight of distilled water. (S= specific weight of the material/ specific weight of water). This implies that if the specific gravity is approximately equal to 1.000, then the specific weight of the material is close to the specific weight of water. If the specific gravity is large this means that the specific weight of the material is much larger than the specific weight of water and if the specific gravity is small this implies that the specific weight of the material is much smaller than the specific weight of water. The specific weight of a gas is generally defined by comparing the specific gravity of air at a temperature of 20 degrees Celsius and a pressure of 101.325 kPa absolute, where the density is 1.205 kg/m^3. Specific Gravity is unitless.

Answer 3

Specific gravity is the ratio of the density of a material to the density of water. The density of water is about 1 gram per cubic centimetre (g/cc). Materials which are lighter than water (specific gravity less than 1.0) will float. Most materials have specific gravities exceeding 1.0, which means they are heavier than water and so will sink.

Answer 4

Specific gravity is the ratio of the density of a substance to a known standard substance, which for liquids is usually water. Something with a specific gravity of 1.1 is 1.1 times as dense as water.

Answer 5

specific gravity : ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances.

Answer 6

It depends on the gravity of the situation.

Answer 7

gravity is the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface (2) : a fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter (as stars and planets), and between particles (as photons) and aggregations of matter, that is 1039 times weaker than the strong force, and that extends over infinite distances but is dominant over macroscopic distances especially between aggregations of matter

Answer 8

The weight in gram of a material which occupies a volume of one cc(cubic centimeter)

Answer 9

it is the ratio of density of a maerial to that of water
so those wich a sp grav less than 1 will float and others with sp grav above 1 will sink

Answer 10

ratio of the weight of a given volume of a substance to the weight of an equal volume of some reference substance, or, equivalently, the ratio of the masses of equal volumes of the two substances.
