UNITS OF PRESSURE IN IDEAL GAS LAW

🔥 Just ONE formula to memorize ALL the gas laws — and that formula is PV = mRT! In this video, fully explained in Tagalog, you will learn how the single Ideal Gas Law equation PV = mRT is the master formula that derives Boyle's Law P₁V₁ = P₂V₂, Charles' Law V₁/T₁ = V₂/T₂, Gay-Lussac's Law P₁/T₁ = P₂/T₂, Avogadro's Law V₁/n₁ = V₂/n₂, and the Combined Gas Law P₁V₁/T₁ = P₂V₂/T₂ — all from one equation, with complete concepts, derivations, units, and worked examples perfect for engineering and chemistry board exam review.

Thermodynamics Made Easy: Isentropic and Polytropic Process Summary

Confused about the isentropic and polytropic processes in thermodynamics? This easy-to-understand summary explains the formulas, concepts, and differences every engineering student needs to know.
In this video, you will learn:
What an isentropic process is
What a polytropic process is
The meaning of the polytropic exponent (n)
Common values of n
Key formulas and shortcuts
Typical board exam questions
An isentropic process is both adiabatic and reversible, meaning entropy remains constant. A polytropic process follows the relation shown above and includes many important thermodynamic processes as special cases.
Perfect for:
Aeronautical Engineering students
Mechanical Engineering students
Chemical Engineering students
Engineering board exam review
Thermodynamics beginners
