Study Notes
Main Focus of Physical Pharmacy
- Examines the physical and chemical principles underlying the formulation and performance of pharmaceutical products.
Fundamental Dimensions of Matter
- Length, mass, volume, time, and temperature are the key dimensions used to express properties of matter.
Metric System Units
- Length is represented in meters (m).
- Mass is represented in kilograms (kg).
- Volume is represented in liters (L).
Reference Standard for Length
- The meter (m) serves as the reference standard for the dimension of length.
Standard Unit of Volume in Pharmacy Laboratory
- The liter (L) is the standard unit of volume commonly used in pharmacy labs.
Practical Unit of Mass in the CGS System
- In the centimeter-gram-second (cgs) system, the practical unit of mass is the gram (g).
Specific Gravity Definition
- Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance, usually water.
Pressure Definition
- Pressure is defined as the force applied per unit area.
Energy Definition
- Energy is frequently defined as the capacity of a body to perform work or to produce change.
Unit of Pressure in the SI System
- The standard unit of pressure in the SI system is the pascal (Pa).
Derivation of Measurable Quantities
- Area, density, pressure, and energy are derived from fundamental dimensions, employing mathematical relationships among them.
Density in the CGS System
- In the cgs system, density is commonly expressed in grams per cubic centimeter (g/cm³).
Specific Gravity in Practical Terms
- Specific gravity is interpreted as the ratio indicating how dense a substance is compared to water, with no units involved.
Unit of Force in the SI System
- The standard unit of force in the SI system is the newton (N).
Mathematical Definition of Pressure
- Mathematically, pressure can be expressed as P = F/A, where P is pressure, F is force, and A is area.
Condition of Energy Relation
- Energy is frequently viewed in relation to the position or state of a body, highlighting its potential to do work.
