Significance of Physical constant
Physical constants are measurable properties that help define the identity, purity, and quality of substances. These include characteristics such as melting points, boiling points, moisture content, and ash values. For example, physical constants are essential for assessing powdered roots of plant species like Cocculus hirsutus and Passiflora foetida, and they are crucial in pharmacological assessments as well. Overall, understanding physical constants is critical for characterizing various compounds across scientific studies and ensuring the standardization of materials.
