1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH. It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol. Both isomers are soluble in simple organic solvents. They are ...

The value of K f, which depends on the nature of the solvent can be found out by the following equation: = R is the ideal gas constant. M is the molar mass of the solvent. T f is the freezing point of the pure solvent in kelvin.
A cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used in castings.
In the case of the Celsius scale (and the long since defunct Newton scale and Réaumur scale) the melting point of ice served as such a starting point, with Celsius being defined (from the 1740s to the 1940s) by calibrating a thermometer such that: Water's freezing point is 0 °C. Water's boiling point is 100 °C.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia. ... Kelvin Celsius Fahrenheit; 1 H ...
The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.
For example, Paraffin has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).
