What else can I help you with?
What is relative density. What is the SI unit of relative density?
The ratio of thee density of a substance of the density of a standard , usually water for a liquid or solid and aur for a gas. The SI unit of relative density is g/ m3
What does gravity spicific mean?
Perhaps you mean "specific gravity". That refers to an object's density, compared to the density of a reference subtance (usually water). For example, if iron has 8 times the density of water, then its specific gravity is said to be 8.
What is specific gravity?
Specific gravity, usually referred to as relative density is the ratio of the mass of a given volume of a substance to the density of a different reference substance. Water is often used as the reference.
Is the weight of an object equal to its density?
No, it's not.Gravity is the force of attraction between objects having mass, where the force on an object is given by the product of the gravitational acceleration and the object's mass. Gravitational acceleration has the units of length per time squared.The density of an object or material is the mass of the object divided by its volume, e.g., water has a density of 1 g per mL. Density has the units of mass per volume.
What units can you use to measure density?
density is usually in some form of mass per volume. so for example you could say grams per cubic inch or milligrams per cubic centimeter.
What changes over time with density?
density changes when the substance changes.
What is the density of banded sandstone?
The density of sandstone ranges quite considerably, usually between 2.0 and 2.6 Kg/m3 (more usually 2.23 to 2.5).
What is the relationship between the density of a substance and its specific gravity?
The specific gravity of a substance is the ratio of its density to the density of a reference substance (usually water). Specific gravity is a dimensionless quantity that allows us to compare the density of different substances without units.
What is tthe measurement for density?
g/mL usually
The density of oil?
Different oils have different densities; usually a bit less than the density of water.
Does liquid have density?
Yes. The density of a liquid is usually close to that of a solid, and much higher than in a gas.
What units are usually used for measuring the density of solids of liquids?
The unit for density is kg m-3.
How can you use density to see if an object can float?
Usually, an object can float if it has a lower density than the liquid it is in.
How is density different from relative density?
Density is a measure of how much mass is contained in a given volume of a substance, while relative density is the ratio of the density of a substance to the density of a standard substance (usually water). Relative density is a dimensionless quantity used for comparison purposes.
How does density change?
Density usually changes when an object is heated or cooled - especially in the case of gases, or when there is a change of phase.
How do you determine the density of matter?
Usually you would use the basic definition of "density": just divide mass by volume.
How does temperature usually affect density?
Density is usually expressed in some unit of mass, divided by some unit of volume. As a result, the SI unit, of course, is kilogram / cubic meter. In this case, water would have a density of about 1000. In practice, it is often expressed in kilogram per liter, or the equivalent, gram per cubic centimeter, in which case water has a density of approximately 1.
