Density Versus Gypsum Added

Chapter 12
1. Increasing or decreasing solubility of the hemihydrateincreasing it means supersaturation of the Calcium sulphate increases and crystals are formed faster. 2. The number of nuclei of crystallization can be increased or decreased:more nuclei of crystallization means faster crystal formation, which means faster hardening. 3. The setting time can be accelerated by increasing

Dilution and Density of Solutions
When we add solute to solution density of it increases, since increase in the mass of solution is larger than the increase in volume. In solid-liquid solutions, density increases with increasing in the concentration of solution. Example: Density of H 2 SO 4 solution, having percent by mass 49 %, is 1,2 g/mL. Find molar concentration of this

BRIX
Definition of Density . The density is the quotient of the mass m and the volume V of a substance (mass density). As the density depends primarily on the temperature, the latter must always be specified. d = m/V [kg/m3] or [g/cm3] More information can be found at: . There is a direct relationship between density and BRIX.

Difference Between Density and Weight
Density vs. Weight. Both density and weight are science-related terms mostly used in the field of physics. However, both terms are not exclusive to the realm of science. The term "weight" is also a word used in the health and medical arena, where it holds a different meaning.

Density of Minerals
Density is an intrinsic physical property of minerals that relates to the composition of the mineral and to the pattern in which the mineral's atoms are arranged. "Intrinsic" means that the property is the same for the mineral, no matter what the size or shape of the sample. In this activity, students will measure and compare the densities of minerals.

Maximum Dry Density of Soil and Optimum Moisture Content
The determination of maximum dry density and optimum moisture content of the soil is a measure of compaction level of soils. This can be measured by mainly two methods Standard Proctor Compaction Test and Modified Proctor Compaction Test.Both the tests help to determine the optimum moisture content that is required for soil to attain maximum compaction i.e maximum dry density

Gypsum: an old product with a new use
Gypsum is the neutral salt of a strong acid and strong base and does not increase or decrease acidity. Dissolving gypsum in water or soil results in the following reaction: CaSO 4 2H 2 O = Ca 2 + + SO 4 2- + 2H 2 O. It adds calcium ions (Ca 2 +) and sulfate ions (SO 4 2-), but does not add or take away hydrogen ions (H+). Therefore, it does

Volume and Density
Using Water as a Density Comparison. When an object is placed in water, the object's relative density determines whether it floats or sinks. If the object has a lower density than water, it will float to the top of the water. An object with a higher density will sink. For example, cork has a density of 240 kg/m 3, so it will float.
