Physical Pharmacy Principles Quiz

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.
