Partial Molar Volumes and Maximum Density Effects in Alcohol–Water Mixtures ADDITION of a monohydric alcohol to water initially raises its temperature of maximum density (TMD) 1–3 . At the same time the partial molar volume of alcohol decreases 4–8 and passes through a minimum. The increase...

Like other molecules, water has a distinct specific heat capacity that describes the heat needed to raise the temperature by 1 unit for one gram of water. From the specific heat capacity of water, we can determine the molar heat capacity using the molar mass of wa...
The molar mass M(A)>M(B) of two substances with the same mass, m(A)=m(B). After chromogenic reaction in the same way, the resulting absorbance is equal, then the relationship between their molar absorption coefficients is ( )A.ε(A)>ε(B)B.ε(A)<ε(B)C

When 10 kcal of heat is added to 2.0 kg of a substance, its temperature increases 20 degree C. What is the specific heat of the substance? What is the formula for specific heat capacity? What are the units of molar heat capacity? What is the molar ...
Accordingly, three strategies are proposed for BFS treatment (Supplementary note 1): BFS-Glassy/Water, BFS-Glassy/Dry and BFS-Crystalline/Dry. The crystallisation ability of SS is quite strong due to the high basicity (CaO/SiO2) and “FeO” concentration, different from BFS. It is difficult ...
