Relative density ( ) or specific gravity ( ) is a dimensionless quantity, as it is the ratio of either densities or weights where is relative density, is the density of the substance being measured, and is the density of the reference. (By convention , the Greek letter rho, denotes density.) The reference material can be indicated using ...
Sodium bicarbonate ( IUPAC name: sodium hydrogencarbonate [9] ), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation ( Na +) and a bicarbonate anion ( HCO 3− ). Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder.
Data obtained from Lange's Handbook of Chemistry, 10th ed. and CRC Handbook of Chemistry and Physics 44th ed. The annotation, d a °C/ b °C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL. % wt. methanol.
Dimension. L 2 ⋅T −2 ⋅K −1. In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. It is also referred to as massic heat capacity or as the specific heat. More formally it is the heat ...
Mass concentration, g/ (100 ml) at 15.56 °C. Density relative to 4 °C water. Density at 20 °C relative to 20 °C water. Density at 25 °C relative to 25 °C water. Freezing temperature, °C. 10 °C. 20 °C. 25 °C.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma ), is a volume-specific quantity defined as the weight per unit volume of a material. A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.
Natron is a naturally occurring mixture of sodium carbonate decahydrate ( Na 2 CO 3 ·10H 2 O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO 3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities.
In thermodynamics, a physical property is any property that is measurable, and whose value describes a state of a physical system. Thermodynamic properties are defined as characteristic features of a system, capable of specifying the system's state. Some constants, such as the ideal gas constant, R, do not describe the state of a system, and so ...
